Rotor / Stator : Modeling flows with rotating reference frame
Hi everyone!
I try to model the rotation of a cylinder (with roughness:look at the attached picture) inside another cylinder (smooth et non rotating) with the purpose of extracting a frequency spectrum of static pressure on the non rotating cylinder wall. My simulation is 2D and unsteady to record the static pressure change. The record probe will be at a fixed point on the stator wall. I would like to know which model is the most accurate in this case (SRF, MRF, MPM ou SMM) ? Best regards! Benjamin http://www.cfd-online.com/Forums/mem...e194-image.jpg |
is this a cfd problem ? is there fluid in the annular region ? how is frequency spectrum analysis relevant to flow simulation ?

Yes it's a CFD problem, there is a fluid annular region between cylinders.
It's a frequency spectrum (static pressure) generated by the rotation of 'steps' (on the rotor) in the annular region. |
Another view of the geometry.
I try to record the unsteady pressure signal on the outer cylinder (fixed). http://www.cfd-online.com/Forums/mem...d-geometry.jpg |
Nobody knows how to use the Sliding mesh Model in Fluent? What's the methodology? ;)
