I got the task to calculate some turbo turbine wheels with frozen rotor.
Some how I have a bug inside my simulation, my efficiency is between 30-40% only. Could somebody show me an example report? I have coupled, SST, Ideal Gas, Air (sutherland law). Turbine boundary has Reference Frame Rotating, Axle def is correct and checked. Tangential Velocity shows no difference (fixed or not). |
