| 摘 要： | 用三维湍流N-S方程及颗粒轨道模型描述水反应金属燃料发动机内部喷雾两相湍流燃烧过程。通过耦合求解气液两相流模型方程,得到发动机燃烧流场。通过模拟Mg与水的反应,分析比较了一次和二次进水方案的不同流场特性。研究结果表明,二次进水方案更有利于火焰稳定和提高燃烧性能。

| Abstract: | Two-phase turbulent combustion process of water/metal fuel motor was described with three-dimensional N-S equations and discrete particles model.The combustion field of the motor was obtained by coupling two-phase equations.The different characteristics of flow field between primary and secondary inlet schemes were analyzed by means of simulation reaction of magnesium and water.The results show that secondary inlet scheme is favorable to stabilization of the flame and improvement of the combustion performance. |
