A Two Dimensional Compressible, Nonlinear Stability Analysis with Applications to the Study of Boundary Layer Transition.

Abstract

A computer program which can investigate the nonlinear response of a compressible boundary layer on a flat plate to any imposed external disturbance has been produced. The program first computes the boundary condition near the leading edge utilizing linear stability theory and then determines the disturbance field downstream as a function of time, utilizing the MacCormack time splitting explicit technique. The program originally created to provide a fundamental understanding of boundary layer response to acoustical disturbances has been modified so that a wide range of parameters can be varied. The effects of Mach number and wall conditions can be computed utilizing the program. (Author)
