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.
