Velocity slip of gas mixtures in free jet expansions

Abstract

A theoretical model is presented for calculating the species velocity of a gas mixture expanding as a free jet through a sonic orifice into vacuum. Calculations were done for two systems (a) a binary gas mixture of argon seeded in helium, and (b) a ternary mixture of uranium hexafluoride isotopes seeded in helium. The results are compared with previous calculations and with experiments.
