Hello Everyone

I am carrying out a simulation of a centrifugal fan. I carried out simulation in normal operation conditions and CFD results showed good qualitative and quantitative agreement with experimental results.

My Boundary conditions are :
inlet: mass flow rate
outlet: static pressure
RPM: 1400
Flow rate : 1.44 kg/s
Fan type: Sirocco Fan
Number of the grid: 2.2 million
Turbulence model: SST




I want to test the fan for maximum total pressure and maximum flow rate condition but I am not sure how the boundary conditions are set are the following test case.

Please let me know what boundary conditions to use for testing :
1. Maximum total pressure condition
2. Maximum flow rate condition

of a centrifugal fan.

Thank you
