Default pressure with velocity inlet boundary conditions
Ashraf Sharara
Posts: n/a

I want to simulate the water flow through a globe control valve. The experimental measurements gave me the values of pressure at the inlet and outlet of the valve. Moreover, the water mass flow rates are also measured during the experiments. The problem is:

With the incompressible flow (water) how to specify the correct pressure at the velocity inlet boundary condition?


Pressure inlet BC gave me correct pressure and wrong mass flow rate

Velocity inlet BC gave me correct mass flow rate and wrong pressure values

Please help and many thanks for all
