interface models
 

Using ANSYS CFX14.5,I try to simulate the unsteady flow in one stage axial compressor.So how to deal with the interface between the rotor and the stator?
Why do my results show that the rotor wake athrough the interface begins to dissipate?:)

If you are doing unsteady flows then you need transient rotor stator. I don't think any of the other options are relevant.

As for the dissipation - that is probably too coarse a mesh.
