✦ Synopsis

A computational technique based on a two-equation turbulence model, coupled with detailed nonequilibrium chemistry, is used for predictions of whether or not secondary combustion of excess fuels will occur in the exhaust of an additive-modified double-base propellant rocket motor. The sensitivity of results to specified input quantities is illustrated. In the near future practical demands for improved predictions may best be satisfied via more precise specifications of certain, identified fluid dynamic and chemical inputs. The inherent limitations of the treatment are discussed: Research in the longer term should especially be aimed at development of realistic descriptions of the process of eddy creation and of hydrodynamics-induced fluctuations in intensive variables.
