Simulating movement of air from low to high pressure in Fluent
 

Hello Everyone,

I am looking at duct in our pump and I want to simulate this duct. The problem is that the inlet region is at a lower pressure relative to the outlet. The flow is also compressible. So I am thinking whether this can be easily done in Fluent? I tried using the outflow boundary at the outlet and a mass flow inlet but this does not work when the flow is compressible. Any suggestions would be appreciated.

Thanks!
Jimmy
