Hi everyone.

I'm tryning to solve a problem with Fluent about an air duct.

The pipe has an inlet and an outlet. The inlet is at atmospheric pressure, while outlet has a gauge pressure that varies in time (a sinusoidal profile). Pressure outlet profile carry the flow from inlet to outlet while pressure drop create the sunction.

I need to find the right BC at outlet, so at time t1, i can close my outlet (like closing a valve in a very short time) and observe the pressure wave coming back.

I'm tryning using "target mass flow rate" , but this condiction doesn't allow a pressure return wave, just try to reach the mass flow rate imposed and pressure and speed with it.

Did you faced this broblem before? how did you solve?

thanks, have a good day!
