摘要: 含湿氢氧掺混燃烧室的动态特性直接关系着水下热动力系统的工作安全性。为了研究该型燃烧室的动态过程规律,基于喷管原理推导出工质流入、流出燃烧室的质量流量,利用质量守恒定律和能量守恒定律得到室内气液相质量、温度变化所满足的方程式,利用液滴群蒸发模型考虑气液相的相间作用,进而完成该型燃烧室动态过程详尽模型的建立。利用该模型编写计算程序,完成某含湿氢氧掺混燃烧室动态过程仿真。结果表明:各仿真曲线能够较好地反映对应参数的动态变化规律,验证了模型建立与仿真的正确性;随着掺混冷却水流量的增加,燃烧室温度降低、压力升高,且温度变化是主要方面。

Abstract: Dynamic performance of humid hydrogen-oxygen non-premixed combustor has a direct effect on the safety of underwater thermal power system. To study the dynamic characteristics of this combustor, the masses and temperatures of gas phase and liquid phase in the combustor are calculated by the laws of conservation of mass and energy, and the interaction of gas phase and liquid phase is considered by the droplet evaporation mode. A dynamic process model of this combustor is established based on the air-in and air-out mass flows of working substance which are calculated by nozzle principle. The dynamic process simulation of a combustor is realized by use of the calculation program based on the dynamic model. The results show that the simulation curves consist with the variation law of parameters during the dynamic process. The temperature in the combustor drops and the pressure in it rises with the increase in flow of mixing water.
