Greetings everyone,
In the derivation of the Favre-averaged energy equation, the total energy comprises of the internal energy, mean kinetic energy and turbulent kinetic energy:  (See Chapter 5.3 of Turbulence Modelling for CFD by Wilcox for derivation)But the compressible flow solvers do not include the turbulent kinetic energy term (k) in the energy equation. Similarly, a few terms on the RHS of the energy equation are also missing. Does any know why this is the case? Thanks for all the help!
