Book excerpt: The thrust of this research program has been the improvement of our capabilities for analyzing stability and transition of boundary layers at supersonic speeds. During the first phase, our efforts were primarily directed toward analytical studies, establishing the elements of the numerical approach, and evaluating existing and new concepts to tackle the variety of problems. The second, and final, phase has been devoted to combining selected elements into codes, verification of these codes, comparison with previous results, and computing the basic flow over realistic geometries. The latter task has consumed the bulk of our resources. Analytical and numerical studies have been performed to investigate the role of the shock on both stability and receptivity characteristics of the flow. Development of the parabolized stability equations (PSE) for compressible flows has been a major goal. A new code incorporating many of the latest concepts and open to extensions is largely completed.
