Abstract
Typical solid rocket motor exhaust emissions consist of high temperature gaseous pollutants including hydrochloric acid, chlorine, and alumina particles. A scrubber is developed to treat the gaseous and particle pollutants present-reducing the detrimental impact of such testing on the environment. A series of water spray configurations are studied to cool the plume without alumina particle modelling. A system consisting of two jets oriented at 60 degrees offers the best performance without compromising safety; the exhaust gases are cooled from over 3000 K to ambient over a distance of 1 meter from the nozzle exit.
