Abstract

The inviscid stability of a small-wavelength, fully nonlinear Görtler vortex state, in a large-Mach number Blasius boundary layer is investigated. In contrast to incompressible flows, the Blasius boundary-layer flow is inviscidly unstable. We consider how the presence of a nonlinear vortex state modifies the inviscid instability properties; some interesting features are found to emerge. The inviscid instabilities could also be regarded as secondary instabilities of the vortex state. This work is a necessary preliminary before the full interaction problem can be addressed.
