摘要

摘要: 为了进一步提升水冲压发动机比冲性能, 基于涡耗散燃烧模型, 建立了高金属含量镁基推进剂水冲压发动机3D多相流掺混燃烧反应模型, 获得了不同进水比例对补燃室内温度分布、组分变化以及发动机比冲等参数的影响规律, 计算结果与地面试验基本吻合。研究结果表明, 一次水燃比对高金属含量水冲压发动机的性能影响明显, 随着一次水燃比的不断增大, 发动机比冲呈现出先增后减的情况, 存在某个最佳的一次水燃比, 发动机比冲性能最高。

Abstract: To improve specific impulse performance of a water ramjet, based on eddy-dissipation combustion model, a 3D multi-phase flow non-premixed combustion reaction model was established for the water ramjet with high metal content magnesium-based propellant. Further, the effects of water-to-fuel ratio on such parameters as temperature distribution and variation of composition in afterburning chamber as well as specific impulse of the water ramjet were obtained, and the calculations are in good agreement with the experiment results. It is shown that the primary water-to-fuel ratio is more important to performance improvement of the water ramjet, and the specific impulse of the water ramjet firstly increases then decreases with the increase of primary water-to-fuel ratio, showing an optimum primary water-to-fuel ratio, at which the water ramjet gains the highest specific impulse.
