Hi Conan,

I'm stuck on the same thing. I'm trying to model a 3D rotating channel on FLUENT. I've tried using moving reference frame (MRF) as well as simple UDF to incorporate coriolis and centrifugal body forces, however I've been unable to validate my results with that of ASME and other papers...

Any suggestions?

Thanks,
