| Abstract: | Four turbulence models, namely, the basic and nonlinear stress-transport models and the basic and anisotropick-ε models, have been tested in the case of interaction between a longitudinal vortex pair and a flat-plate boundary layer. The results of their predictions were compared with Mehta and Bradshaw's measurements. In this paper, part of the results involving those of the nonlinear stress-transport model and anisotropick-ε model are presented and discussed.
