Combination of mass flow inlet and pressure inlet boundaries
I want to simulate the flow and outflow on a rotating disc by using the VoF-model in FLUENT. For the inlet of a liquid phase I have to choose the mass flow boundary condition over the disc. The second phase is air by normal environment (pressure and density).
My problem is that I have no idea how to configure the boundary condition for the environment. Itīs possible to define this outflow area (outflow for the liquid phase) with the pressure-inlet condition (with gauge-pressure of 0 Pa) and a mass flow rate of air of 100%?
In a first solution I got convergence, but I donīt know whatīs about the physical correctness.
Also I tried a combination of mass flow inlet, a pressure inlet from above the plate and a pressure- outlet for the outflow on the disc side (also with gauge-pressure of 0 Pa). But in this model I got divergence.
Iīm thankful for each help
