Abstract:

A prototype computer program has been written to calculate three dimensional viscous compressible flow past bodies in relative motion. The program solves the Navier-Stokes equations using multiple zones of mesh. During the Phase I research and development effort, routines were written to allow the meshes to move and to couple the solutions in adjacent zones along sliding boundaries. The importance of a well planned software structure was demonstrated. The code a was applied to a turbine rotorstator interaction problem. Keywords Three dimensional flow Navier Stokes Viscous flow Compressible flow Zonal flow Unsteady flow Computer programming.
