Numerical Simulation of Goertler/Tollmien-Schlichting Wave-Interaction

By National Aeronautics and Space Administration

The problem of nonlinear development of Goertler vortices and interaction with Tollmien-Schlichting (TS) waves is considered within the framework of incompressible Navier-Stokes equations which are solved by a Fourier-Chebyshev spectral method. It is shown that two-dimensional waves can be excited in the flow modulated by Goertler vortices. Due to nonlinear effects, this interaction further leads to the development of oblique waves with spanwise wavelength equal to the Goertler vortex wavelength. Interaction is also considered of oblique waves with spanwise wavelength twice that of Goertler vortices. Malik, M. R. and Hussaini, M. Y. Langley Research Center NAS1-18605; RTOP 505-90-21-01...
