Set inlet velocity and pressure in cavitational model
Hello people,
I want to set the BCs in my venturi tunnel set with a cavitational model. my intial condition are: V= 18 m/s P0 = 39700 Pa When I set the cavitational model I have to put at 0 the operating pressure so I cannot modify it. I tried to use the pressure inlet. I assumed that the: gauge total pressure = total pressure the supersonic/initial gauge pressure = static pressure so using this formula: p_0 = p_s + 1/2 ro*v^2 p_0= total pressure p_s= static pressure v=velocity ro=density I should find my static pressure and put those values in the inlet right? But unfortunally in postprocessing I don't have in the inlet the velocity that I want or better that I thought I imposed. Please help me Best Gerardo |
Sorry for the delay and thanks for your help.
here is the case and data file: https://dl.dropbox.com/u/8252311/Sez_gola_Press.zip Ps: I just noticed that even if I change the supersonic/initial gauge pressure the result doesn't change it's like fluent is not considering it. |
