在低温实验法的液体的成穴的数字模拟在在液体燃料火箭改进推进系统的稳定的操作是重要的。它也代表液体近正在操作到它的批评的点的问题的一个更宽广的班，成穴的热效果是显著的。由实现“完整的成穴模型”模仿低温实验法的成穴的现在的文章焦点，结合了精力方程，与在本地温度的真实液体性质的反复的更改一起。稳定的州的计算然后分别地在液体氮和氢在水翼船和葱形饰上被进行，基于哪个我们与热效果探索成穴的机制。在象由另外的研究人员的以前的计算一样的模拟结果和试验性的数据之间的全面比较在低温实验法的液体验证完整的成穴模型。到成穴数字的洞长度的敏感也被检验。

英文摘要：

Numerical simulation of cavitation in cryogenic fluids is important in improving the stable operation of the propulsion system in liquid-fuel rocket. It also represents a broader class of problems where the fluid is operating close to its critical point and the thermal effects of cavitation are pronounced. The present article focuses on simulating cryogenic cavitation by implementing the ＂full cavitation model＂, coupled with energy equation, in conjunction with iterative update of the real fluid properties at local temperatures. Steady state computations are then conducted on hydrofoil and ogive in liquid nitrogen and hydrogen respectively, based on which we explore the mechanism of cavitation with thermal ef- fects. Comprehensive comparisons between the simulation results and experimental data as well as previous computations by other researchers validate the full cavitation model in cryogenic fluids. The sensitivity of cavity length to cavitation number is also examined.
