Set inlet velocity and pressure in cavitational model
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
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
Sorry for the delay and thanks for your help.
here is the case and data file:
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.
