Research in Computational Fluid Dynamics.

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 MacCormack's 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.
