在某低温液体火箭发动机汽蚀文氏管内部空穴流动现象分析的基础上，建立了空化泡动力学模型，基于FLUENT 软件进行汽蚀文氏管内部气液两相流的数值模拟，数值模拟介质分别为水、液氢和液氧，并将模拟结果同水调试验和试车数据进行比较。结果表明，数值模拟的技术应用为汽蚀文氏管的设计奠定了理论基础。

Based on the analysis of the internal two-phase flow phenomena in the cavitating venturi of a cryogenic liquid rocket engine, a cavitating bubble dynamics model is established, and gas-liquid two-phase flow is numerically simulated based on the FLUENT software, with the simulation mediums of water, liquid hydrogen and liquid oxygen. The simulation results are compared with datas from water test and hot test, showing that the application of numerical simulation technology laid a theoretical foundation for the design of the cavitating venturi.
