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: https://www.sharcnet.ca/Software/Flu...ug/node244.htm 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 |
