Non-linear interaction of Goertler Vortices and Tollmien Schlichting waves

In this paper spatial Direct Numerical Simulation is used to study the nonlinear interaction between planar Tollmien Schlichting waves and Goertler Vortices. The results show the development of lambda vortices typical of K-type and H-type break down. Two different structures have been found which are shifted with respect to each other by pi in the spanwise direction. (AU)
