大叶片板式贮箱是当前最为先进的一种新型贮箱,大叶片板式结构是该贮箱推进剂管理的核心部件.对微重力条件下大叶片板式贮箱内流体行为进行了数值仿真和微重力试验验证.采用液体体积分数法(VOF,volume of fluid)两相流动模型数值模拟板式贮箱内流体流动特性,得到了流体分布规律.搭建了大叶片板式贮箱缩比模型试验系统,对板式贮箱内流体行为进行微重力落塔试验,得到微重力环境下流体特性.数值仿真和试验结果表明,大叶片板式贮箱在微重力环境下管理流体性能良好,大叶片板式结构为空间流体(包括低温流体)管理提供一种良好的途径.同时本文仿真和试验为国内板式贮箱设计提供了必要的支撑数据.
The large-blade plate tank is the most advanced new type of tank at present, and the large-blade plate structure is the core component of the tank propellant management.Numerical simulation and micro-simulation of the fluid behavior in the large-blade plate tank under microgravity Gravity test.The fluid distribution characteristics were obtained by numerical simulation of two-phase fluid flow model with VOF (volume of fluid) model, and the fluid distribution was obtained.The model test system of large-blade plate tank shrinkage ratio The results of numerical simulation and experimental results show that the large vane plate tank has good performance of management fluid in microgravity environment and the large vane plate structure is space fluid (Including cryogenic fluid) management.At the same time, the simulation and test provided the necessary supporting data for the design of domestic slab tank.
