The schedule is very tight, maybe next time. Thanks for watching

@digguscience okay 💛 ...

Thank you for watching

Wikipedia defines it as: “In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime.” So, we get a basic idea that eddies are some sort of structures that ‘swirl’ or ‘twist’ or ‘spin’. Two of the great books in fluid dynamics define eddies as follows: 1. “Identifiable structures in a turbulent flow, particularly those that spin are called eddies.” - Fluid Mechanics, Authors: Pijush K. Kundu, Ira M. Cohen and David R Dowlin 2. “An 'eddy' eludes precise definition, but it is conceived to be a turbulent motion, localized within a region of size l, that is at least moderately coherent over this region. The region occupied by a large eddy can also contain smaller eddies.”- Turbulent Flows (Stephen B. Pope)

A vortex refers to a swirling motion of fluid or air, typically characterized by a center of rotation. Vortices can be observed in various natural and man-made systems, such as tornadoes, hurricanes, whirlpools, and even in the wake behind a moving object. Vortices are typically three-dimensional structures with a well-defined axis of rotation. On the other hand, an eddy is a localized swirling motion within a fluid or air flow. Eddies are often found in turbulent flows and can be thought of as small-scale vortices. They are typically two-dimensional structures and do not have a well-defined axis of rotation like a vortex. Eddies are transient and tend to form and dissipate within a fluid flow. Although both involve swirling motions within a fluid or air, however, they differ in terms of their size, structure, and longevity.

I eat rice. Everyone eats rice. Where does the rice come from? Of course, the rice comes from farmers. Something similar does not mean it comes from the same source, just as any farmer can plant rice without needing to know where the rice comes from.

I think almost all UA-camrs experience it. Keep working, making better and better videos.

Glad you liked it!

Maybe next time, right now I'll do some videos about vector analysis. @DigguScience

It was true. The Reynold number can be used to determine whether the fluid flow will be laminar or turbulent.

Thank you for watching this video

@@digguscience I didn't. I watched the first five seconds and then I knew that it would be all bullshit after that. Why would I waste my time on your bullshit? ;-)

Happy learning. Thank you for watching.

My answer, T = 2π√(m/3k)

You are right. If I have free time, I will immediately make a revised version

This material is conceptual and abstract. This seems similar to the Lagrangian and Eulerian concepts. In the volume control approach, we choose to analyze the fluid in a fixed volume, even though the fluid particles in that volume are different fluid particles. In the systems approach, we only analyze the behavior of the same particles. Like gas fluid in a balloon. The volume of the balloon can change, but the number of particles in the balloon remains the same. Regards

Thank you for watching

@@digguscience what software do you use for these animations and presentation?

Thank you! Cheers!

Because a number that looks zero doesn't mean zero. keep the enthusiasm to work better.

Thank you for the additional data.

@@digguscience ur video editing is so good, what software do u use.

Hope it is useful

Thanks for subbing

Thank you! Cheers!

Glad you liked it!

Glad to hear that!
