Density problem using cavitatingFoam
Hi to everyone,
it is my first post. I have been looking for a solution in this forum, but pitifully, I haven't found it. My problem is: I am using the cavitatingFoam solver to solve an injection case. This case is about a specific injector, which don't allow cavitation. I have set the boundary conditions for velocity and pressure as follow: Pressure Inlet: totalPressure; Outlet waveTransmissive; Velocity Inlet: pressureInletVelocity; Outlet: zeroGradient; I am using a k-epsilon RAS model for turbulence. I want the density to remain constant, applying the boundary conditions as fixedValue at the inlet and outlet in the value of 743.61 kg/m^3. But the problem is that at the outlet, the density value decreases to 600 kg/m^3 and I don't know why. Is it due to the boundary conditions? Could someone help me? Thank you |
