centrifugal fan

giannivr

Dear all, I would know if one of you have ever modeled a centrifugal fan with Fluent, like this example: http://www.fluent.com/solutions/auto...ifugal_fan.pdf

The fan that I'm studying was tested in laboratory and I'm trying to validate the CFD model (like in the example).

I'm using the same approch: steady-state multiple reference frames, standard k-e for turbolence, incompressible working fluid (air).... But my results are not in good agreement with test data, especially for low flow-rate.

If anyone have experience in similar CFD model, please contact me.
