I'm currently working on a simulation case with multiple centrifugal fans in a system to blow the air. I have a few questions:

1. Regarding the static pressure in a centrifugal fan curve, what does it represent? For axial fans it is very straight forward because I can simply use a 2D surface as the fan and the pressure difference between two sides of the surface would be the static pressure. Since centrifugal fan has separate inlet and outlet surface, then what's the definition of the static pressure?

2. I want to simulate centrifugal fans without considering the blades. If I know the fan curve, then generally how to set up the BCs for the model? Thanks for your help
