Abstract
Numerical simulation of the steady two-phase flow field of gas-particle inside a JPL nozzle is described in this paper. The computations use a time-dependent technique using the TVD-MacCormack algorithm for both gas and particle phases. The nozzle flows considered here are inviscid, and spherical particles of 1-5μm in diameter are treated. Numerical results show that the nozzle expansion is delayed as the interaction between gas and particle phases becomes strong. In addition, it is seen that there exists a particle-free zone in the divergent section of the nozzle.
