Hi all,
I am trying to simulate the flow driven by an high-pressure industrial fan in a duct. The ideal BCs would be: -inlet: p = 111325 U = 10 -outlet p=101325 U = inletOutlet or similar (just to assure mass conservation -walls: p zeroGradient; U fixedValue uniform (0 0 0 ). I understood that it is not possible to set up these BCs in simpleFoam, so I am trying to use rhoSimpleFoam (see case in attachment). I tried any possible combination of BCs my mind came up with but I could not get meaningful results, could anyone enlighten me on a proper setup? |

im not expert about compressible flow
but in incompressible flow when u set pressure, use pressureInletVelocity for velocity

thank you for the reply, in fact this works with incompressible but the same BCs do not work for compressible!
I don't know if it's the BCs or something related to numerical schemes! |
