how to set BC for compressible flow target mass flow rate
I have a T shaped geometry. One inlet and two outlets.
Total flow rate is 500 slpm. The flow ratio for the outlets is 9:1.
I am using compressible flow to solve the flow.
inlet: mass flow intlet
outlet: pressure outlet with target mass flow rate turned on.
However,after 100k iterations, I still cannot get expected mass flow rate through the two outlets.
Could anybody give me some suggestions about this?
I also had problems with pressure outlet and traget mass flow rate (see http://www.cfd-online.com/Forums/flu...flow-rate.html)
and here is how fluent does it:
In your case I would just use pressure outlet without traget mass flow rate and adjust the gauge pressure until you get your mass flow rate
