Computation of Three-Dimensional Time-Dependent Flow Using the Euler Equations

Abstract

The development of a computer program to solve the three-dimensional, unsteady Euler equations is described. A finite volume method in Cartesian coordinates is used with the MacCormack predictor-corrector algorithm. The grid imposed on the computational domain is topologically equivalent to a regular grid on a cube. The resulting control volumes are hexahedrons with quadrilateral faces. Solutions are presented to show the accuracy of the computer program and to demonstrate the degree of flexibility with respect to complex model geometry.
