Check valve boundary conditions

bjsl · February 5, 2017, 13:40

Hi guys,
I'm trying to model a system where the inlet an outlet are check valves, i.e flow only moves in one direction through the boundaries.
The inlet flow is based on the pressure inside the chamber (in my case created by a change in volume). Is there a boundary condition suitable for this?
Particularly no backflow through the outlet.
I am trying to avoid modelling the check valves in a dynamic mesh.
Thanks!

Hi,

Were you able to solve this problem? I want to do a similar thing for a UDS.

Thanks
