摘　　要：水反应金属燃料发动机系统构型研究需要以燃烧数值模拟作为研究基础.基于FLUENT软件,建立了水反应金属燃料发动机内多相湍流燃烧仿真模型,开展了二维轴对称数值模拟研究.计算研究和分析表明,燃气发生器加补燃室结构的水反应金属燃料发动机流场结构复杂;喉径变化对液滴掺混效果、金属颗粒燃烧效率和液滴蒸发效率影响显著.The water/metal fuel motor system configuration is based on a numerical simulation of combustion. Using the Fluent software, the multi-phuse turbulent combustion simulation model in the water/metal fuel motor was established and the 2D axis symmetrical numerical simulation was achieved in this article. The calculation and analysis results indicated that the water/metal fuel motor flowfield of the gas generator adds the secondary combustor chamber is complicated. It is also indicated that the changed throat diameter has a remarkable influence on the effect of water droplet intermingle, the efficiency of water droplet evaporation and the combustion of metal particles.
