摘要
采用热力计算与数值仿真计算相结合的方法,对高铝含量推进剂水冲压发动机内流场进行了计算,并对温度、比冲等参数进行了对比分析.分析结果表明,数值仿真结果与热力计算结果能够较好地吻合,通过热力计算可以对发动机和推进剂的能量特性进行优化,数值仿真计算能够准确地反映铝基金属燃料水冲压发动机内流场的分布规律,对高铝含量推进剂水冲压发动机的设计具有指导意义.
Abstract
The internal flow field of water ramjet with high aluminum content propellant was calculated by using the method of combining thermal calculation with numerical simulation,and the temperature,specific impulse and other parameters were analyzed.The analysis results show that the numerical simulation results are in good agreement with the thermal calculation results.The thermal calculation can optimize the energy characteristics of the engine and propellant,and the numerical simulation can accurately reflect the distribution of the flow field in the aluminum based metal fuel water ramjet.The results have guiding significance for the design of the high aluminum content propellant water ramjet.
