Stability of Boundary Layers at High Supersonic and Hypersonic Speeds

Abstract

The goal of this research is to improve our capabilities for analyzing stability and transition of boundary layers at supersonic speeds. During the previous reporting period, efforts were directed primarily toward analytical studies, establishing the elements of the numerical approach, and evaluating existing and new concepts to tackle the variety of problems. This reporting period was devoted to combining selected elements into codes verification of these codes, comparison with previous results, and computing the basic flow over realistic geometries. Analytical and numerical studies were performed to investigate the role of the shock on both stability and receptivity characteristics of the flow. Development of the parabolized stability equations (PSE) has continued. A new code incorporating the latest concepts is largely completed.
