Improved Blade Stall Predictions

Results with the Proposed length scale:


RANS                                                        DDES                                              DDES (new length scale)

More Details

              Improved drag and moment predictions

  • RANS  dramatically over-predicts eddy viscosity
  • DDES-SSM: lowest eddy viscosity values
  • Leading edge separation near transition location
  • DDES-Max: separation starts near trailing edge
