Since UA-cam is about to delete annotations, figured I'd post them here for everyone to see. Enjoy the video!
1:59 Whoops, this is meant to be an increase in pressure, not a decrease in pressure, my bad. Click on the card for more detail on the adverse pressure gradient.
What about the different types and shapes of rear diffusers?
Can vortex generators be used without a wing to reduce drag?
On the rear roof of the car or even the decklid?
@@ChargedTTq Vortex Generators are meant to keep the air that passes through your car attached to the boundary layer. Without them, at certain high speeds your air starts to disperse at the top of the car right before the roof slopes down. In a way they can reduce drag, but not a whole lot cause you still need other parts to help reduce drag.
Can u explain how vortices are created by vortex generator
UA-cam deleted my subscription for here too
Thanks for the lesson Ryan Gosling!
maddudenyc 🙌🙌
He looks like Daniel Radcliffe too!
maddudenyc You win! 🙌🏻 lol
I was thinking that the whole time
@@ThePivoteer101 he's a hybrid, shall we name him Ryan Radcliffe or Daniel Gosling?
as every genius engineer must, you draw terribly. awesome explanation
He was using his left hand at an awkward angle
As a fellow left hander, we draw shit on purpose. If all our powers were on display, you would burn us at the stake. 😜
My professor met those standards 😂
better to have the brains than drawing skills ask the docs ahahahahahahahahahah!!! you need a bucket to dribble all your shit in to
Some people are sometimes unreasonably difficult to please. You’re getting a Mercedes F1 engineer explain things to you FOR FREE and you still find things to complain about. Unbelievable
I really appreciate the credentials. It's nice to finally see someone on youtube who actually knows their $hit. +1
It was that the credibility was presented which was awesome
Amen.
Agreed
Simon WoodburyForget well he got scouted to work for mercedes in the aero division in formula 1 so i think he knows what he’s doing
@@dandingerat exactly, I really dont understand why people like this simon call him idiot
yeah it is not some aerospace level of explaination but 99,9% wouldnt get it really or wouldmt care enough to watch
My favorite part of the video was when you set everyone on fire by proving you have you paper in this field.
Greatest ooof moment of all time
I've used this video as a supplemental explanation for my students in aerospace physics. Great job!
mildly informative? bro free engineering classes 🙌 bless your soul haha. I was at ASU studying mechanical engineering joined, FSA too but couldn't wait to build my own stuff. Hence I'm attending a top notch fabricating school. your videos are immensely helpful. I hope to get my fabricating UA-cam page going soon 👍 video editing in process.
Subbed. I'm expecting good things from you, Andre. ;)
you got that channel?! id sub
;)
This video was quite helpful to me! It made it a lot easier for me to understand what vortex generators do and how they improve the airflow. Looking at this from an aviation perspective (specifically improving the stall characteristics of wings) this was an incredibly helpful video explaining how that works. I was previously confused as to how disturbing the airflow over the wing could work to improve the stall characteristics, but now it all makes sense! Thank you very much for your highly informative video!
When you brought up the example of what they thought when designing the EVO´s aerodynamics I understood exactly how it would play out. It basically helps the wing to do it´s job more properly to push down the rear end for down force.
Excellent, Kyle!
I appreciate your diligence and hard work bringing aerospace to the masses
This was very helpful and informative! Thank you for taking the time to explain them!!
Outstanding videos. I'm an aero mech engineer myself, and have a huge passion towards aerodynamics. These vids are like crack to me. Keep 'em coming!
Nice work man! U alongside with Engineering Explained make a perfect duo for enlightening us and making our automotive knowledge expand to respectable degree. Thanks
Would love to see examples of the different types of vortex generators you mentioned in a future video. Thanks for these, nice work!
Best aero explanation out there! I'm looking to implement this tech for wing sails, endplated, Sail GP style. They use a double slot wing with a essentially a huge adjustable flap at huge angles. Ive never seen vortex gens on them. As you say, every little helps!
really good video. you did not have lots of materials in the video but still the explanations were very much clear enough.
Great presentation. As an aviator instructor, it helped me to understand and provide an excellent example for explanation.
Thanxx bro.. finallyyy got it. Have been trying to understand VG , after watching a lot of videos, yours made complete sense. Thanks
I so love getting knowledge from someone who actually has some. Thanks for sharing.
Damn I hate the room where you are speaking... that sound tho...
Drl2t if you don't like room echo then speed up the video, it speeds up the reverb decay.. I thought it would be engineers watching these 🤦♂️
@@bungcheese5901 hopefully no audio engineers and sound designers are watching this. That being said the video is very informative but the echo takes away from the quality
Yes.
I made a helpful comment to him on how to correct this problem.
As he is a top notch petsonality, I'm certain he will be on it immediately.
Sir, you just efficiently described the major parts of my aerodynamics course. Bravo
I had no idea there was such a thing. I learned something completely new and your explanation was clear and concise. Subscribed!
New subscriber, love this. Informative, interesting and best of all. It's understandable.
I will never look on a race car the same again.
love your work. im a new subscriber and absolutely love what you do.
you remind me of Engineering Explained, but you go more in depth in real world workings rather than just concepts.
You have no idea how much your video helps me with my term paper.
Thanks,
I have an interest in aerodynamics, esp. for cars, so these videos are very crucial. Thank you for making these.
Thanks, Will look to your trainings before the aero
stages on the Jag.🏁
Best to you Scott Whitmire
Love what you do, man.
As a supportive comment, I'd like to mention there is a science or two on being able to hold the attention of the viewer/listener.
I'm talking about audio quality.
The ghastly echo in your voice recording which you created by relying on the built in mic of your camera...several feet away, can be easily solved by clipping a small mic to your lapel. You could also use a boom mic just out of your shot, but since you move around a lot, you"d need an operator. In other words, to hold the attention of even seriously interested, technically minded viewers, you need a mic close to your mouth. This will help you present your world class information in a world class manner.
Once again, love the great contribution to racing education that you make.
That was explained exceptionally well. Thank you!
Wow this video is amazing. I'm writing a paper on Vortex generators for my minor project and this surely helps!!
Best one yet. Love the beginning, chopping up the haters :). Great stuff Kyle. Keep on sharing the knowledge please. Regards JW
Cheers mate, Very helpful and good and the Explanation along with applying the Scientific Proof of what Vortex Generaters do. 💯
Took me a while to find you. Like your videos. iRacer here PCA coach, so working with aero is new to me. Running a Merc AMG GT3 car. Thank you- it has got me thinking. --S
Did he just predicted that Civic type R will have the vortex generator
Just discovered your videos, love them bro!
Man I'm in love with your videos, keep it up
You got a subscriber and a like from me. Thank you and please keep it up, this has been informative and it made complete sense. The reason I watched the video is because I am trying to improve my car for autocross and I wanted to learn about vortex generators. This was exactly what I needed. The only question I have left to answer is do they make more of an impact at higher speeds, my inclination is to say yes as it is probably easier to measure the impact they make at higher speeds vs lower speeds, but the effect they have is present regardless of speed, therefore I think it is wise to install these if your goal is to improve track times. Also I like the bit where you explain the "flaw" behind the evo designed vortex generators, as they are not the most efficient vortex generators, so I should do some research and find vortex generators that actually work before making a purchase. If you have a recommendation on a manufacturer of aftermarket vortex generators that would be superb (or you could always make them yourself, as I am sure you could make a competing product. Also wouldn't you think it help improve track times if vortex generators were installed at every angle?).
Hi, I watched your entire video. I don't know anything about this science but found your explanation interesting. Good video.
I'm Currently studying to become a aviation maintenance engineer... i had a hard time understanding exactly how vortex generators suck high energy air into the boundary layer... You said the exact same thing my instructor said in his explanation, but just seeing you use a diagram while you explained gave me an epiphany... thank you
Great video! Highly informative.
Sir you got a subscription very informative thanks and keep up the good work
Thanks for the explanation ! Appreciate your work
This has helped me alot in regards to understanding this phenomoinon.
Great videos - Would love something that goes a bit more in depth on what types of vortex generators the average person might DIY in their garage for a budget limited race car.
F**k the haters, keep the information flowing!!! (no pun intended)
This is the problem with people. Asking for his background or a source is not "hating" it's common sense.
the fact you said "(no pun intended)" suggests it was intended.
It was intended to not be intended. :D
Nice video, good explanation for low velocity air flow. High velocity appears to react very differently, flow separation always occurs.
Nicely done!
I really wish more people who think they are gear heads were informed like you are. I have watched videos of people going down the road with there coors beer in there buddys truck calling out every car with any aerodynamic mod on screaming that they are a racer. I would have not know what a Swan Neck Wing was if it was not for your video. You make perfect sense when you explain. keep up the good work
Nice info. I had no idea! Thanks!
Most enlightening, great stuff ... I like seeing cars with VGs and no spoiler. Hehehe ...
This is a trip back for someone who just started watching your stuff recently. (I like the beard, fyi)
Very interesting ! Thanks for the explanations
good video very informative, if i could make a suggestion it would to reduce the echo from the room when filming.
+Kc Ros Check my new vids, the problems have been solved! Thanks for watching!
Love the trenchcoat, good info too. Thanks.
Great video, I've subscribed and am going to watch your other videos. Thank you!
When I was a Truck Driver we put Vortex Generator on the aft edge of the cabs and Trailers and the difference that made to stabilizing the vehicles was very impressive, and the unexpected fuel saving was a surprise but very welcomed.
Very helpful video. I am interested in the aeronautical application for VGs and your video explained it nicely. Be it a car or airplane wing the same principal applies, just you car guys want the lift downwards and we airplane guys want it the other way.
Thanks for a neat video.
Thank you, it was very illustrative.
You really do need A LOT more subscribers. So in-depth stuff compared to any car related videos on youtube.
Engineering Explained needs to collab with him
Why would somebody say you don’t know what your talking about? I have an aeronautical science degree and I enjoyed the refresher. Thank you! Great video!
Thanks for the information Kyle. It led to me do a lot more research to understand how they work. I realized that a vortex generator is useless on my car and possibly counterproductive.
That was absolutely brilliant... Spot on =)
Excellent Lecture. A+. Thank You.
This is awsome!!
Great job
Dude your videos are awesome!!
Thanks very much for this video. In between people like yourself, and being given a copy of 'Race Car Engineering by Paul Van Valkenburg' when I was 8, I feel more confident in making aero changes to my race car, because I feel like I might have half an idea what I'm doing now, as a privately funded person without oodles of cash or a wind tunnel.
Kyle, very well explained. Could you perhaps make a video to explain this concept on another application, be the edge of a bicycle tire. Mavic came out with the CXR and CX01 blade that smoothens the surface area where the tire mounts the rim, yet insisted on using their tire which has tiny ridges to create a gradient vortex at the leading frontal edge of the tire. In trying to understand their design and science I came accros this video. I would be curious to better understand where tp make this vortex on the edgw to have the greatest effect
Trust me , i know what im talking about 😂 i love this guy already
thank you very very much for your time and your explanation
I enjoyed it and I done a learn. Thanks.
Lool that flex in the intro 💪🏾 tells me i came to the right channel 👍🏽
Thank you for sharing great work 👍🏿

muchas gracias, se aprecia mucho tu contenido, Saludos desde México.
Great explanation!
Love the content. I used to have a Very-EZ airplane that had a canard wing.
Great explanation ! Thank you !
I see vortex generators on airplanes that need increased short take-off performance also. Thanks for the informative vid. Now i have a better understanding of how those devices work.
Can you do a video on vortex generator profiles and what different profiles can be used for? Awesome channel btw. Really good info.
Great explanation! helped a lot, thanks! :)
aerodynamics tips for better fuel economy please. that would be a great topic that everyone could apply.
Ryan East anything that reduces drag?
@@WetOlde I too would like to know more about Vortex Generators for improve MPG on my daily driver.
Which one's work, and how do I acquire them.

@@michelletessin6702 remove your rear wing, automatically improve your MPG!
@@lindltailor not in every case, in sedans rear wing can reduce drag
@@lindltailor dont have a rear wing on my ioniq
Thanks for the brilliant set of videos realted to aerodynamics....YOUR CHANNEL IS SUBSCRIBED........PERIOD.....
Hi Kyle, Great You Tube Channel, it is very informative. It is nice to find knowledge freely shared. Keep it up mate.
I have a couple of questions on VGs and drag reduction on my 4wd wagon tow vehicle and caravan combination. I am planning on making the mods myself and hope to reduce fuel consumption and increase stability. I have found quite a bit of info but a lot of the detail is kept secret for sales purposes I guess. Anyway, I have three main ideas. Please consider them and let me know what you think. 1. the most obvious mod is a deflector foil placed near the rear of the roof of the tow vehicle. I will guess the angle to be about 40deg and 500mm long. I was thinking of using long threads to view the air flow in real life. The idea would be to have the air flow join with the flow over the van roof. Would VGs on the deflector make any difference to how far the flow goes before dissipating? 2. I have read that VGs placed along the rear edges of the van will assist with reducing drag on the rear of the van. Do you think that is a valid idea? I cannot decide if it is good or bull so I need a wind tunnel to test theory. If it is valid what type of VGs would you use and what spacing? 3. Failing the VGs on rear edges I thought about using a partial boat tail, angled at 10 deg and about 750mm extended. Your thoughts would be most appreciated.
best regards and keep up the excellent channel, cheers n beers, Mick
I 'd love a tutorial on airflow of engine ports on heads, both intake as well as exhaust. you certainly know your stuff!
there's a reason why the art of port flowing is called "the black art", there are many more variables affecting the gas flow, even good CFD software can struggle to accurately depict what happens in a port, head, and combustion chamber...
that was an incredible explanation
Thx alot for explain and presentations
Fantastic. I had never heard of vortex generators.
super informative ..nice vid bud
Old vids are still informative. Wish I was an aerospace engineer majoring in race car dynamics. I'm just a home hack with no money trying to build race cars in my spare time.
Good for you! At least you're doing something. Something that will go fast and make happy noises.
I'm just a home hack with no money taking youtube engineering classes because I can barely afford to maintain the nearly stock vehicles I have lol
@@BrokeWrench I've not modified a vehicle in 16 years. I buy cars that are specced well enough that I can just drive them with no maintenance. Lol. Funnel all my money into my track car.
Plus I have a deal with my wife that ant of my sideline projects go into my race fund. I buy rusty old trailers and fix them and sell for profit and part out cars I get for cheap
Thanks for the great lesson.. i just can recommend you to put some echo and reverb dampening material into the room to improve acoustics.
Hey Kyle, that was very Informative,thanks.
Wanted to more about how they design deep space shuttles, satellites considering if the dense space shock waves with abrupt pressure gradients come into the the picture and the shuttle being in no aerodynamic orientation?
Watched this video of yours again Kyle just after watching a young person installing “vortex generators” on his car. Thought to myself, someone once correctly explained vortex generators before and this young person hasn’t got it quite right. This young person certainly didn’t watch your video Kyle, poor show! :-) Then right at the beginning of your video you show the exact same mistake as I’d just seen. Yes I did have a chuckle. So glad someone knows what they are talking about. I’m trying to decide where to install vortex generators on a model sailplane that suffers with scary tip stall at slow speeds. Would you suggest vortex generators in front of the ailerons or at the 40% chord? Great, well presented video Kyle. Great style and not afraid to put people right. Very good. More thumbs up for your video Kyle.
Thank you so much, that helped me a lot. I'll be having my exams on this coming week. I'm an aircraft maintenance engineer.
very interesting - some more on this subject please :)
You got my like on the intro, i cannot wait to hear more :)_
Hi Kyle, could you do a video on the usage of vortex generators for flow stabilization on trailers? I am designing a very light camper trailer (to be towed behind a sedan). In order to minimize potential for dangerous sway oscillations from aerodynamic buffeting, I have already minimized the frontal area and rounded the edges and corners. However, strong, pulsating side winds still scare me. I am wondering if strategic placement of VG's can alleviate these drag effects and make the trailer tow more calmly. My tongue loadings and Cg are nearly perfect, and I have both electronic and mechanical anti-sway; I am trying for reducing the condition which induces sway in the first place.
MUCH BETTER!
Frankly after watching your '30 second' explanation i couldn't stop scratching my head and thinking WTF?
I understand now :)
Great videos! Thanks man!
Well done. Was reading an article in the LA Times about Jet Blue retrofitting its A320's with vortex generators to reduce noise as the planes descend into the Long Beach airport. Begged the question "what is a vortex generator?" Your video provided the answer. But does beg another question..."are there any potential adverse outcomes to installing vortex generators on aircraft wings"?
this was mildly informative. Thanks ^^
