HP Turbine boundary Condtions?
I have a 3d stator-rotor HPT stage grid. I am not sure whether I am using the correct BC's to study the interaction. Rotor blade : Wall Stator Blade: Wall Rotor Hub: Wall Stator Hub: Wall Rotor Inlet : Pressure Inlet Rotor Outlet: Pressure Outlet Stator Inlet: Pressure Inlet Stator Outlet: Pressure Outlet

Mixing Plane: Stator Outlet- Rotor Inlet

Here is what I am not sure about

Pitchwise boundary of Stator Grid - I am using periodic BC will it be rotational periodic or translational periodic

Pitchwise boundary of Rotor grid: Will it be rotational or translational periodic

Mid Spanwise cutting plane parallel to hub : I am using symmetry but I have a 3d curved profile. Think this is not the one I should be using.

Any help?
