Abstract:

An analysis is presented of compressible viscous flows past wavy walls, without restricting the mean flow to be linear in the disturbance layer. Linearization of the compressible disturbance equations results in a system of six first-order differential equations for the perturbation quantities. The method of orthonormalization is used to control the error growth in the numerical solution of these equations. The present results agree more closely with experimental data than the results obtained by using Lighthills theory, which restricts the mean flow to be linear in the disturbance layer.
