Abstract

A calculational comparison of a free molecular plume code (HAPAIR: High Altitude Plume-Atmosphere Interaction Radiation) and a Monte-Carlo Plume Code (TRAMP: Transitional and Rarefied Axisymmetric Monte-carlo Plume) is made for a selected sequence of cases going from a free molecular (Kn = 15) to a highl transitional (Kn = 0.07) flow regime. Results are presented which document the breakdown of free molecular flow assumptions in the transition regime and show the effect on the critical physical processes responsible for plume emission.
