摘　　要：研制的火箭发动机一维喷管非平衡流通用计算软件 ,建立在一个统一的化学反应库之上。该通用计算软件可对推进剂元素为碳、氢、氧、氮、氟、氯的火箭发动机喷管进行一维化学非平衡流数值模拟。通过计算推进剂元素为氢、氧和碳、氢、氧、氮的喷管一维化学非平衡流 ,得到了喷管流场的速度、温度、密度、压力及各组分的质量百分比等参数 ,为工程设计提供了依据。The general computational software of rocket engine one dimensional nozzle nonequilibrium flow , which is based on one unite chemical library, can simulate the flow field of rocket engine nozzle with the propellants consisted of carbon, hydrogen, oxygen, nitrogen, fluorine, and chlorine elements. By computing the nozzle flow field with the propellant elements of hydrogen, oxygen and carbon, hydrogen, oxygen, nitrogen, the fields of velocity, temperature, pressure and all species mass fraction were gotten. They can be referenced by designer.
