ONE DIMENSIONAL FLOW OF A GAS PARTICLE SYSTEM

Abstract

A family of solutions to the equations governing the one dimensional flow of a gas-particle system are presented. The basic assumptions upon which the theory is based are that the particles do not interact (distance between particles large compared to their size) and that the particles are spheres and are always in Stokes flow regime (small particle lags). It is shown that this family of solutions corresponds to flow in a nozzle in which the axial velocity gradient is a constant. As this condition is approximately realized in the throat region of most nozzles, it is believed that the theory has general validity near the nozzle throat. The design of a nozzle for use with a gas-particle exhaust system is also discussed.
