Abstract

The nonparallel flow effects on roughness-induced perturbations in subsonic boundary layers over a flat plate are explored within the scope of the linearized Navier-Stokes equations. The receptivity problem is treated under the parallel flow approximation, and the nonparallel flow effects on the perturbations development are taken into account. The analysis is based on the method of multiple scales when intermodal exchange due to the nonparallel character of the flow is neglected. The nonparallel flow effects lead to lower velocity and higher temperature in the wake downstream from the hump.
