Turbulence: An introduction

In this video, first, the question "what is turbulence?" is answered. Then, the definition of the Reynolds number is given. Afterwards, the relationship between the turbulence and the energy cascade concept is explained, and finally, the turbulence CFD simulations are discussed.

    Very Good and Clear Presentation! I wish every teacher could explain this well, I had a Calculus Professor who did this well which combined with a Small class size was perfect for me. Thanks for the time and effort that you put into this work. You could do a Book and a Set of DVDs. Or an online Interactive book/series!

    Thank you very much. Very well explained. Was very helpful for me, was lacking this basic understanding of the three approaches to turbulence.

    Great video! Would you be able to suggest any papers discussing the three methods in more detail?

    Dear @MaxBiella, thank you for writing. I would recommond you to have a look at the following book: Computational Methods for Fluid Dynamics - Ferziger and Peric

    So basically in the energy cascade the TKE is transferred by large eddies to smallest ones near the wall which dissipate their energy contribution into heat by viscous forces. At the stage what is going to happen? For example, If I have a flow into a pipe with a large turbulence intensity is the flow able to heat the wall of tube?

    I don't think this scenario is possible, heat is actually "microscopic" kinetic energy.
