- 对低温流体预冷充填管路开展动态特性仿真研究可为低温液体发动机启动方案的制定提供重要参考。为获得低温流体预冷充填的主要特性,对能量方程及充填率对流方程进行空间一维求解,对质量方程及动量方程进行集总参数求解,建立了准一维有限体积的预冷充填模型,并对主要影响因素进行仿真研究。对不同初始壁温的影响研究表明:随着管壁初始温度的升高,液氧对管路的预冷时间逐渐增长,蒸汽建压时间缩短,压力峰值逐渐增大; 由于气体的缓冲作用,在低含气率的液氧充满管路时充填水击压力逐渐减小。对液氧、液甲烷及液氮预冷管路的仿真结果表明:在相同稳态流速下,液氧预冷时间较快,液甲烷次之,液氮的预冷速度最慢。
- Abstract:
- Simulation on the dynamic characteristic of cryogenic fluid pre-cooling pipelines can provide an important reference for the development of cryogenic engine starting scheme.In order to obtain the main characteristics of cryogenic fluid pre-cooling filling, a quasi-one-dimensional model with the finite volume method is established.In this model, the energy equation and the filling rate convection equation are subjected to a spatial one-dimensional solution, while the mass equation and the momentum equation are solved by the lumped parameter method.Then the main influencing factors are analyzed.The study on the influence of different initial temperatures of the pipe wall shows that with the increase of the initial temperature, the pre-cooling time of liquid oxygen on the pipeline gradually increases, the steam pressure build-up time decreases, and the peak of gas pressure increases gradually.Due to the buffering effect of gas, the filling water hammer pressure decreases gradually when the liquid oxygen with low gas content fills the pipeline.The simulation results of liquid oxygen, liquid methane and liquid nitrogen pre-cooling pipelines show that under the same steady-state flow rate, the pre-cooling speed of liquid oxygen is faster, followed by the liquid methane, and then the liquid nitrogen.
