Hi,

Below will be the description of the 3D axial turbine.

The geometry of the turbine is based on NASA 67 rotor (hich is an axial compressor). Currently (15/06/2023) only the rotor part is modeled until mixing plane would be available.
The model represent a single blade (1/22) and cyclic AMI is used.
The mesh is polyhedral with tetrahedral generated by Salome (NetGen) then converted to polyhedral with polyDualMesh (script generateMeshUNV) with only 93460 elements. I have tested Snappy but the solver crashed even with a very good mesh quality according to checkMesh.

I was not able to have a stable solution with rhoSimpleFoam but, thanks to ICSFoam shared by Hakan, the case finally converged. That means that you have to compile ICSFoam solver to run it.

Next update will be the adding of the stator.

Feel free to leave your comments or feedback.
