Hi, thanks for the great video! Could you possible make a savonius simulation inside a pipe? and derive power graphs and power coefficient graphs with RPM? That would be a huge help. There is a gap in existing videos!
Super useful video thank you :) I am having an issue though - when looking at the result in CFD Post the only flow with changing variables is within the rotating region, the rest of the flow is stationary. The streamlines also don't seem to appear. Any idea what I might've done wrong?
Modeling a fan in CATIA or Solidworks is gonna be hectic. I suggest you try openVSP where you give in parameters and the model is done. And then import it to Ansys
Listen here there will be no boundary conditions because we are simulating the effect of propeller blade on almost stationary air so propeller rotates it will suck in air and leave out
Even though it might be too late, what he did was ctrl+a (selected all faces), then deselected the outside faces to get the blade. You can also do it by use box select in face select mode

I did a lot of research on UA-cam but I couldn't find it, but thanks to you I found it, thank you.
this is actually very useful for me thanks a lot
Sir, in this you gave the mesh motion i.e angular velocity to turbine but how to calculate the rpm of turbine by giving the wind speed.
Which version of ANSYS are you using? I have ANSYS 16.0 and it looks quite different. What do I do?
bro what steps are you doing in 8.40 for selecting just the propeller because i triy to do it but the whole inner domain is delected.
Ctrl+A and then Ctrl+F all surfaces of the solid until only the propeller remains
@@irisdumutel3371 heyy is there any way i can contact you i need the same help , i am stuck here 😭
@@irisdumutel3371I didn't work out for me can you please help me?
why did you mirror and translate the object at the start?

what is the total simulation time it takes ?
does the rotating disk have to be a revolve? I did it as an extrude
Could please make a video of complete drone analysis please 🥺
but when you have a rotating domain, are you not also artificially rotating any air that goes into that domain? or is only the mesh rotating?
Good question, I am wondering the same thing.
Olny mesh
which ide and tools used
I followed exactly what you did but after the calculations part the propeller cylinder gets tilted
Ive noticed that my K and Epsilon are not converging how do I fix that?
Nice, but how calculate the rotation of turbine as efect from wind speed?...
Can you show, how calculate dynamic / static structure analysis of turbine blade on ansys
*& noise analysis in ansys
Assalaamu alaikum bro. Have you been able to do this please?
There are some ERRORs. Mainly in mesh and setup. This result is not valid. My main concern is the setup.
Hi please can you do step by step exhaust fan simulation and Fan rotation animation for air
Do you have any tutorial for modeling the geometry of the fan?
Modeling a fan in CATIA or Solidworks is gonna be hectic. I suggest you try openVSP where you give in parameters and the model is done. And then import it to Ansys
Why is there no audio commentary?
Hello
Where could I find the results in order to load the results ?
What were the boundary conditions?
same question

Do we have to mirror prop and then delete it
For multi propeller purpose

Hey my simulation is happening for only initial and final time step. Where is the problem?

How we can find Force caused by flow
Hi! Would you be willing to share this simulation file for personal use?
Can i ask ur geometry bro?
Can anyone tell me the step he did on 8:40 min when he turned it transparent and selected the blade
have you found how to do it? mine's isn't worcking
Even though it might be too late, what he did was ctrl+a (selected all faces), then deselected the outside faces to get the blade. You can also do it by use box select in face select mode
Why did you not use LES ?
Too high of fidelity I guess
do you have propeller file 15x4? can give me?
Hello! What did you do in time 8:40 ?
Select all
@@BharathaBhaskarat 13:45 which choice did you select?
@@BharathaBhaskar Pls send me your details got an urgent job for you.
@@BharathaBhaskar HOW DO YOU SELECT ALL? AND HOW DO YOU DESELECT THE SURFACE UNTIL THE PROPELLER SHOWS UP?
@@hongngew2811 you can hide the faces that poses problem for the vizualization and select propeller by step
thank you i love you
Is it possible to share it's/STP file?
where is inlet?
