Abstract

A kinetic nucleation model is developed that avoids modeling termolecular collisions and determining the collision complex lifetime. The developed kinetic nucleation model is integrated into the direct simulation Monte Carlo (DSMC) code to simulate homogeneous condensation in a free-expanding plume. It is found that condensation phenomenon has a significant impact on the flow field and therefore cannot be disregarded. For higher stagnation pressures, gas number density decreases much faster along the plume center line compared to the lower stagnation pressure cases.
