Default Need help with BC's for a internal flow problem
Posts: n/a

I am trying to simulate a internal flow problem using Fluent 6. It is a 2D problem of flow inside a closed cylinder with small openings at both the ends. Fluid is forced through the openings at one end and leaves the opening at the opposite end. Since the holes are small in comparison with the cylinder diameter, the fluid leaving the cylinder through the other end has to be sucked out. This needs to be modelled as suction BC at the outlet. Is there a way to give 'SUCTION' BC using Fluent?. Any help is appreciated.

thanks, ravi.

Use a pressure outlet BC and set the gauge pressure lower than the operating pressure.
