Instability of laminar wall jets along curved surfaces
Abstract
Linear perturbation theory is used to analyze centrifugal (TaylorGortler) instability in wall jets along curved surfaces. Two types of centrifugal instability are studied. The region between the wall and the maximum in velocity profile is defined as the inner flow, while the region beyond is designated the outer flow. Type I instability means that the flow is along a concave surface and the inner flow is unstable. Type II instability means that the flow is along a convex surface resulting in an instability of the outer flow.
