Abstract : The Direct Simulation Monte Carlo technique has been used to investigate the detailed flow structure in the region near the lip of a nozzle flowing to vacuum. The results for a range of nozzle lip thicknesses and shapes for argon are presented. Keywords: Monte Carlo, Rarefied gas dynamics, Plume, Nozzle flow, Contamination, Plume signature.
