- 摘要:
- 采用数值模拟方法对液氧贮箱增压过程进行研究。贮箱内流场采用流体体积函数(VOF)多相流模型考虑，选择标准双方程k-ε湍流模型分析湍流效应，气液两项之间的热量、质量转移通过自定义程序(UDF)求解。获得了贮箱压力、排液流量、气垫温度、液氧温度对贮箱内流场温度分布的影响。计算结果表明，在稳定增压过程中，贮箱液面无扰动，贮箱内温度分层分布；各参数变化时，对贮箱内温度分布的影响主要是温度梯度的变化，并且各工况下液面附近和扩散器附近温度梯度基本相同。
- Abstract:
- Pressurization process of the liquid oxygen tank was studied with a numerical simulation method. Volume of fluid (VOF) model was used for flow field inside the tank. The standard k-ε turbulence model was selected to analyze the turbulence effect, and a user-defined function (UDF) for phase transition was used to solve the heat and mass transfer between the liquid and the ullage gas. The effects of the factors including the tank pressure, mass flow rate of liquid oxygen, ullage gas temperature and liquid oxygen temperature on the temperature distribution of flow field inside the tank were obtained. The calculated results show that the liquid surface has no disturbance and the distribution of the ullage gas temperature is stratified in the steady pressurization process; the main influence of the factors on the temperature distribution is the variation of temperature gradient; and the temperature gradient near the liquid surface and the injector is almost the same in different working condition.
