Model Description for the SOCRATES Contamination Code

Abstract

The SOCRATES contamination model is described at length. The model allows for unsteady or steady simulation of contamination aboard the space shuttle orbiter via the direct simulation Monte Carlo method. The basis for the model is discussed, and sample calculations are given for an RCS engine firing at 200, 250, and 300 kilometer altitudes. The dependence of return flux of scattered species on exhaust species molecular weight is elucidated. Contamination, Monte Carlo, Space Shuttle.
