- Abstract
Numerical simulations of three-dimension two-phase flow field of tail-pipe nozzle SRM were carried out using Euler-Lagrange model. Influences of different particle diameter, axial and lateral acceleration, and aluminum percentage powder on particle distribution characteristics were analyzed. The results show that the difference between gas flow field and two-phase flow field is evident; with the increasing of particle diameter, the particle concentration increase, and the change of particle movement rule is obvious; the change of acceleration markedly influence particle distribution of grain segment, inconspicuously influence tail-pipe segment; lateral acceleration is more distinctly influenced particle trajectory and concentration than axial acceleration; with the increasing of aluminum powder percent, the particle concentration rise.
