I am running an open channel flow case in OpenFoam (using interfoam). It is a simple two-phase (water and air) flow over a bump (image below).
Given that the flow is subcrtical at the inlet and supercritical at the output I expect the height of the flow to decrease over the bump and remain the same thereafter. But I am getting different results. Is there a problem with these boundary conditions: Volume Fraction : zero gradient inlet and outlet. Velocity: Fixed value inlet and zero gradient outlet Pressure: zero gradient inlet and fixed value (p_rgh =0) pressure outlet. |
