Computational Simulation of Rocket Engine Testing in Self-Pumping Altitude Diffuser Flow

Coauthors: Harvey Smith (LMSO)

Simulation of the mixed supersonic/subsonic flow inside a self-pumping altitude diffuser used for rocket engine tests at NASA/SSC is attempted using a CFD code developed by the MSU ERC. This work represents a revival of the effort to predict this real world complex flow problem. The results of basic parametric studies considering engine power level, bleed mass flow ratios, and modeling detail will be presented. The modeling capability enhancements required to simulate the full problem will also be presented and discussed.
