which model is proper for the co-axial disks flow

joanna

hello,everyone! i have been working on an Open rotor¨Cstator disks flow for some time ,mainly using gambit and fluent. the flow structure is as following: a core region is gathering near the axis of rotation,which is radially stationary but brought on rotation by the disks, the fluid is pumped outward by the rotor disk and the external fluid is ingested into the gap region along the stator disk. A long re-circulation may appear, and there is a small vortex appears near the rim.

i don't have much experience in this kind of cfd, if somebody knows something about what i was said ,would you please give me some advice on the choosing of calculating software,which one is more proper,fluent or cfx? and which model will be more accurate,NRG or RSM or what else? Thank You for any suggestions. Regards joanna
