LONGITUDINAL VORTEX PAIR IMBEDDED IN A TURBULENT BOUNDARY-LAYER - COMPARATIVE PERFORMANCES OF SEVERAL TURBULENCE MODELS

Four turbulence models, namely, the basic and nonlinear stress-transpo rt models and the basic and anisotropic k-epsilon models, have been te sted in the case of interaction between a longitudinal vortex pair and a flat-plate boundary layer. The results of their predictions were co mpared with Mehta and Bradshaw's measurements. In this paper, part of the results involving those of the nonlinear stress-transport model an d anisotropic k-epsilon model are presented and discussed.
