摘要：
Various droplet/wall interaction models and a deposition model accounting for deposition, rebound and splash modes for ducted rockets were analyzed and deposition for ducted rockets were numerically simulated and experimentally investigated. The result shows that deposition for ducted rockets is mostly focused in the zones such as the head-end of secondary combustion chambers, downstream inlet and convergent section of nozzle. The particle size distribution has a great effect on the depositing position, and the deposition velocity at the nozzle throat computed from pressure-time curve is agreeable to numerical simulation results.
