Turbulent Swirling Flow in Combustor/Exhaust Nozzle Systems

Abstract

A Computer code named DUMPSTER was developed for the analysis of the viscous swirling nonreacting flow in dump combustors closely coupled to convergent divergent nozzles. The development, application, and use of this code is described in this report. DUMPSTER solves the 2D/axisymmetric compressible Navier-Stokes equation with one or more transport equations for trace chemical species. Turbulence is modeled with either an algebraic model or a two-equation K-E model. The equations are solved using a time-dependent finite-volume method. The fluxes are calculated using on of the following second-order accurate flux functions: (1) Steger-Warming flux vector splitting, (2) Roe's flux difference splitting, or (3) Harten-yee's Total Variation Diminishing (TVD) Flux. The results of the code agree reasonable well with dump combustor experimental data and other numerical simulation programs.
