Reynolds or Ensemble Averaging?
 
Hello. I am running an unsteady problem with the Spalart-Allmaras Turbulence model. Does Fluent use Reynolds-Averaging or Ensemble-Averaging for this formulation? I thought it was RANS, but my professor says otherwise....

I think: If a periodic unsteady flow, RANS results are Ensemble-Averaging. IF a steady flow, RANS results are Reynolds-Averaging.
