Hi,

I am simulating water flow in a tube containing a concentric smaller and shorter tube with FLUENT (turbulent). So the water flows through both the smaller tube and the annulus. How can I obtain the mass flow rate in the annulus and the flow rate in the smaller tube?

I tried inserting a plane (cross-section) without bounds and use the Function Calculator in CFD-Post to calculate the mass flow across the plane, but the result gives the total flow rate. Anybody knows how to obtain the two flow rates?

Thanks,
Vinson
