Abstract
A non-local stability theory is presented which includes the effects of streamline, surface and wave trajectory curvature on instability waves in three-dimensional, compressible flow. Only convectively unstable flows are considered. It is shown that both basic flow and metric gradients in more than wall normal direction require a generalized wave ansatz which leads to a set of spatial, non-local stability equations to be solved. Also wave trajectory curvature in the surface-tangential plane is shown to be governed by non-local stability theory.
