I wrote a code for 3D flow in transonic flow compressor. FVM and cylindrical coordinates are used. The convergency of radial momentum equation is significantly badly as of other equations. Axial projection of the hexahedral control volumes (quasi orthogonal surfaces R-theta) shows partially highly twisted geometry.

I think it must be applied some correction in the radial flux calculation. I tried some but without succes.

DO SOMEBODY KHOW, TO DO IT?

Hi,

I have a working code (Euler in cylindrical coordinates) for multistage turbomachinery with Unsteady Sliding mesh technique. I am interested in selling the code with source for some fee. If interested please contact.
