Module 5 :
Lecture 16 : Some Scaling Relations
 


Scaling of small scale structures

We shall look at the scaling of small scale structures that determine dissipation in a little more detail. We start with the definition of dissipation

 

We further note that small scale turbulence tends to be isotropic.

We shall pay special attention to some specific aspects of dissipation
