I think there is something wrong with my simulation. I am getting a very high flow rate (8x higher than expected). I used for my boundary conditions at the inlet, Pressure Inlet and for the Gauge Total Pressure I put 101325Pa. For the outlet, I chose the Pressure Outlet, and the value assigned for gauge pressure I put 101725 (which is 101325 + 400). I also chose the target mass flow rate option and I put the value for the expected flow rate which should 12.1m^3/s.
I have got these values from the fan performance curves that I already have and I want to produce the simulation to get something similar from the simulation (so on my fan performance curve attached in the first post the volume flow rate is 12.1 at 400 Static Pressure.
Is this correct or I got them all wrong? Can you please guide me on how to choose the right boundary conditions for this simulation?Thank you so much!
