COMPRESSIBLE BOUNDARY LAYER STABILITY BY TIME INTEGRATION OF THE NAVIER- STOKES EQUATIONS AND AN EXTENSION OF EMMONS' TRANSITION THEORY TO HYPERSONIC FLOW

Abstract

The paper presents results from two separate studies related to transition. The first part describes boundary layer stability calculations based on the direct numerical integration of the Navier-Stokes Equations with respect to time. The purpose of reformulating the stability problem in the present manner is to avoid the inherent linearization of the classical method. The study that led to the present results is viewed as the initial phase of the development of a numerical method capable of treating transition itself, although it is too early to say just how far into the transition zone the method can be extended. The first phase of such a study consists of developing adequate numerical techniques for the integration and for representing boundary conditions. The second part of the paper presents an application of Emmons' transition theory in hypersonic flow.
