Thank you! Exactly what I needed. I also found the book for this work: Pope, S.B., 2000, "Turbulent Flows." Chapter 6. But it helped me to see you working from it.
Thanks for the great video series. Question here: say the eddy is translating with velocity u in the x direction...which is the characteristic velocity of the eddy and how do we measure it....does the probe have to move with the eddy at velocity u and then measure the rms of the three fluctuating components over a specific period of time?
Good evening sir How are you -I I hope you are good ; I have a question please: I want you to tell me how many method to model turbulent flow and it is the best way? What is the problem of closure And there's how do they model? I hope you reply to my questions thank you
Thank you so much for providing gorgeous lecture about turbulent. By the way, how can I derive dissipation rate equation (epsilon = 2 nu S_ij S_ij )? What I understood is that, dissipation rate is the rate of turbulent kinetic energy transformation to thermal energy. So is it right that dissipation is due to shear stress? Then why is it square of S_ij?

great introduction! Thank you so much for your hard work, Prof. Jorg Schluter
Thank you
Great course of lectures
Very good lecture!
Thanks for the good explanation!
Thanks for your lecture.!!!!!!!!

Amazing :) :) :)
Thank you sooooo much.

That term can be best understand when you derive mean kinetic energy equation. Follow kundu and cohen for more
