modified mean kinematic pressure ??
for pisofoam with k and epsilon model, the isotropic part of the Reynolds Stress is absored into the pressure gradient terms. Thus they become pmean/desinty+2k/3, where k is turbulent kinetic energy. According to my understanding, openfoam treats them as a group in the code as follows:
solve(UEqn == -fvc::grad(p));
My question is: is the pressure that is output by Openfoam actually pmean/desinty+2k/3 or just pmean? Thank you very much.
