boundary conditions for induced flow?

December 27, 2007, 17:09

Hi, I'm want to simulate an induced flow caused by an jet flow. I have two tubes (inlets). Both tubes join into a tube with a slightly bigger diameter with the outlet at it's end (it's similar to an Y-shaped piece). The one inlet is a velocity inlet. Now I want to find out the velocity (and the mass flow) of the induced flow. What would be a good boundary condition for the second inlet (the induced flow)?

no idea?

Hi,

Try giving Pressure Inlet, Its only a guess.
