Thank you Herr Schulter. Very amazing tutorial. I still have one question, at 18:07 you defined dissipation rate with Kolmogorov scales, but you also mentioned before that the dissipation rate can be known from the energy transfer rate when it’s in equilibrium and then we can calculate the scales. So which one exactly is known and which is unknown?
Hi, many thanks for these videos - you're a life saver! Please would you repeat what you say at 16:20 about why Re = 1 is the limit? Can't quite make it out, and I don't know enough about convective(?) flow to work it out for myself!
Thank you so much for this wonderfully made series of videos, they were very helpful!

i hope if you help me about my project about kolmogrov theory

Thx mr Schulter

first video which i really found very efficient on turbulence...........

Just do the algebra, by calculating the Reynold number in terms of the defined Kolmogorov lenght, time and velocity...it's equal to 1.
Thanks a lot :)
Amazzzzzzzing.
this is a hypothesis or reality? isotropic?
