Numerical Solution of the Three-Dimensional Unsteady Euler Equations

Abstract

A user's guide is presented for the three-dimensional, time-dependent Euler code, ARO-1. The guide provides a brief theoretical background for the explicit MacCormack algorithm and its application to the Euler equations. The main routines of the program are described and the calling order examined for a sample computational step. The primary code variables are defined, along with the nondimensionalization employed. Specification of the initial and boundary conditions is discussed from a theoretical and practical perspective. The required input data are presented for a sample case. This report serves two purposes: to introduce the principles of computational fluid dynamics to engineers and scientists unfamiliar with this subject and to provide detailed instructions on the use of this particular computer solution of the Euler equations.
