simulation of ceiling fan
 
Dear All

I am trying to simulate a 3 bladed ceiling fan. For this I am using MRF approach.I am assuming a cube as room and at centre of it the fan is placed at some distance(without any support). Then a cylinder is created around it enveloping the fan. A tet mesh is generated. The air volume inside cylinder is given fan rpm and the walls an absolute rotation of 0. K-epsilon model is used.

Please let me know if the approach is correct & what kind of pressure contours are expected above & below the plane of the fan. Also any comments on turbulence modeling are welcome.

Thanks

Raj
