This confined environment is used in order to allow direct comparisons with realisable 3D Navier-Stokes computations avoiding ‘infinite’ spanwise conditions. The flow is investigated in the critical regime at ..

Hence, the main objective in industrial computational fluid dynamics (CFD) is to increase the capabilities for an improved predictive accuracy for both complex flows and complex geometri
