lotd is on a distinguished road
I have to calculate pressure ratio of high pressure turbine. Turbine is a part of jet engine.

I have doubts if it is possible to count that in fluent because I'm not sure if Fluent can solve case when the stream should move rotor blades.

I have data like:
- pressure before turbine
- mass flow rate
- blades rotation speed

In my case I set:
- pressure-based, Steady
- K-epsilon, Realizable, Enchanted Wall Function
- moving frame with rotation-Axis Direction (1,0,0) and Rotation speed 870 [rad/s]
- BCs: pressure-inlet, pressure-outlet, rotation vector of walls (1,0,0), periodicity
- Scheme: Coupled, Gradient: G-G Node Based, Pressure: Standard, Momentum & Energy: Second Order Upwind, Turbulence Kinetic Energy & Turbulence Dissipation Rate: Power Law

I would like to ask You if that settings are correct. What's more I would like to know if should add rotation speed -870, because I know this is how it should be done with compressors.

I am looking forward to hearing from You,
