Hello members

Please help me with the following simulation. I have to carry out simulation of an HVAC duct with (A) duct of 1600 x 900 mm and two ducts (B) & (C) of 700 x 2100 mm ducts. I know the following conditions at duct B. 886 m3/min flow.

Also, I have a duct system with slight modifications in the outlet duct design.

1. In the first condition duct (B) is entirely closed.
2. In the second condition duct (B) has a 10% inlet flow of the entire volume.

How to set up this simulation.

Also , while comparing two different design of duct how to setup boundary condition so that the cases can be comparable.

Can I setup mass flow rate at the outlet and check for pressure drop for both cases ?
