Case: Periodic Channel flow at Re_tau =1000
Method: Large-eddy simulation. Version: OpenFOAM/v2206 Problem: The postChannel utility overpredicts the RMS velocity in the spanwise and wall-normal direction. Refinement and increasing expansion ratio did not improve the results, as shown in the figures. Solution: Code:
#PostProcessing #To get the smooth profile, the columnAverage should be done first postProcess -func columnAverage -latestTime >& log.columnAverage postProcess -func sampleUMean -latestTime >& log.sampleUMean postProcess -func sampleUPrime2Mean -latestTime >& log.sampleUPrime2Mean |
