I'm trying to simulate the flow in a well and pump system as shown below
outlet ^ | | surface | | | | | | | -----| | | | inlet | | | --> | | | -----| | | | | |_________| | | | |________________________| The flow enters from the inlet to the well and exits from the outlet, where a pump is pumping the flow out. The well is exposed to the air. Now I kown the inlet velocity and the approximate surface elevation in the well, but I don't know the outlet pressure caused by the pump. So what kind of BC is better for the outlet? Simply outflow? or pressure outlet(but the pressure is not available)? |
