I'm trying to run an airfoil in ccm+ inside a 60 degree far field at a wall rotation of 63 rpm's to calculate velocity distribution across the blade. The issue I'm having is with the boundary conditions, currently I'm trying to run pressure outlet and pressure outlet but it is pulling air in from both outlets..

open to suggestions

or how to set up the simulation with boundary conditions only knowing rpm's

maybe u figured already your problem out, but try velocity inlet and pressure outlet, this should be working.

You can also define the flow direction on your boundaries more deeply, just look at the physics conditions (if i remember right)
