Abstract

Two major questions arise. First, how is the kinetic energy of turbulence maintained? Second, why are vorticity and vortex stretching so important to the study of turbulence? To help answer these questions. First, derive equations for the kinetic energy of the mean flow and that of turbulence.

In this chapter, the derivation of two – dim. K.E. was presented in full details and then mads assumption to find out the solution of the equation in simple way. The approximated velocity profile with strong pressure gradient and at the separation point are presented.


Keywords: Separation point, TKE, Two dimensional, Velocity profile.
