Fan Question


I have a box, and there’s a circular inlet for that box from a fan. I know the fan operates at 1000cfm at 1500 pa static pressure. My question is, do i set the boundary condition of the inlet as velocity inlet with a volumetric flow rate equal to 1000 cfm or do i set a pressure inlet of 1500 pa? I’m a little confused about how to use the two in conjunction.


Hello duunoebruh,

we usually use fan curves to simulate this relationship between the volumetric flow rate and the pressure.

You can learn how to set up a boundary condition like this here:
