Hello, I am trying to model the flow of air moving from ambient into a pipe that is connected behind to a vacuum pump. The pump has a fixed pumping capacity of set mass flow rate/velocity. What I am not sure is how to model the inlet BCs. The whole system is atmosphere and the inlet mouth of the pipe is outlet of the domain I am interested in.
Can anyone throw a hint on how I can model this problem at the atmosphere end? Thank you Sandilya |

If its moving from ambient use total inlet pressure at inlet of 1 atm. For exit use target mass flow rate then you will see negative gauge pressure at exit if operating pressure is set to 1atm.
