Abstract
A simple approach to the estimation of rotational relaxation times and collision numbers in supersonic expansions based on the use of the th ermal conduction model is presented. Expressions are derived for the c alculation of these quantities and relaxation times are calculated as a function of mean kinetic temperature and axial distance from the noz zle exit for the homonuclear diatomic species H-2, N2, O2 and Cl2.
