benoe is on a distinguished road
Hallo I'm trying to simulate a turbulent puff structure in pipe. I insert a jet disturbance trough a sink and a source on the wall. I try to use the coupled solver but the massflow is getting less. What can be the reasons?
(when use the seggregated solver the puff-structure dies out.)

Thanks for help
Bene
