Hi guys,

Actually i need to produce distortion on the inlet of axial compressor and i need to study the effects on distortion . In actual compressor test they will follow some methods like Mesh Distortion Screens , Air Jet distortion generator. Even in most journals they have talked about the Distortion screens only. But these methods will consume some very Higher grid points it seems . we have facility only to do simulation with maximum of 8 million node counts. We have tried to produce distortion with porous domain at the inlet of the compressor. It has not given much satisfactory results for us. So any one suggests some methods/techniques to produce the distortion. I have attached some images which might be useful for you to get an idea...
