hi my friends
please help me i have a convergent-divergent nozzle boundary conditions are: pressure inlet=550 kpa gauge pressure outlet= -50 kpa gauge when i run fluent and after convergence pressure in throat is equal for example -500 kpa and we know this is wrong because the absolute vacuum is -101 kpa why do this happen in fluent and how i prevent from this error? for both compressible and incompressible flow please help me |
