Development of a Novel Free Molecule Rocket Plume Model

Abstract

This paper describes development of a set of analytic point source transient free molecule equations generated to model behavior ranging from molecular effusion to rocket plumes. A brief review of model performance for step function mass expulsion will be followed by presentation of physical extensions to include the effects of an ellipsoidal molecular distribution to account for certain types of thermal nonequilibrium and response to sources described by pulse as well as step function behavior.
