Hi, I've a incompressible and turbulent flow field to solve (energy equation switched off). Anyone can tell me which is the meaning of PTHERMO=PSTATIC-(2/3)*ro*k ? If we consider the TOTAL PRESSURE = PTHERMO + PDINAMIC + ro*k i don't know exactly why I had to subract (-2/3*ro*k) to the global value ? Is it a turbulent dissipation ? Where it comes from ? Thank you very Much Mat.
