Numerical analysis of an unsteady confined supersonic jet

摘要

A numerical calculation technique to analyze the time-dependent flow field induced by a supersonic jet expanding into a confined volume is presented. The expanding, developing jet flow and the complex flow pattern within the confining volume are described by the unsteady, compressible, Navier-Stokes equations. The equations are solved using a MacCormack explicit predictor-corrector type of numerical technique. The analysis is applicable to a family of problems including flows within certain solid rocket motor configurations and thermo-electric energy conversion systems.
