Abstract:

The objective of the work was the investigation of improved numerical methods for solving fluid dynamic flow problems. Accomplishments include 1 derivation of a generalized second-order two-step numerical method, 2 modification of the dispersive behavior of MacCormacks method, 3 analysis of numerical oscillations at a shock wave, 4 derivation of a selective strong diffusion technique for eliminating numerical overshoots at shock waves, and 5 development of various useful computational codes. A research contract covered the computation of several supersonic flow problems of interest.
