Hello, I have found that p_rgh is often used in OpenFOAM.
According to Henrik thesis (4.21) p_rgh=p-rho*g*h "the modified pressure p_rgh is obtained by removing the hydrostatic pressure from the pressure." I think rho*g*h is not the static pressure, as rho is not a constant, thus it should be int(rho*g)dz. So the question is what's the physical meaning of p_rgh. |
