Fuel tanks are a core component in satellites that manage the propellant. This study numerically analyzed the fluid transport with parallel guide vanes in a vane type surface tension tank. Flow3D was used to simulate fluid transport in microgravity in a scale model with 15% liquid filling rate with comparisons to experimental data. Then, the simulations were used to compare the leading edge climbing speed for various working conditions and the liquid volume below a specified cross section for various liquid filling rates, various numbers of vanes. The results show that the liquid climbing process on the guide plate in the plate tank can be divided into the liquid level repositioning stage after the gravitational force is suddenly removed and the stable fluid transport stage. Throughout the entire capillary flow stage, the liquid leading edge climbing rate is not related to the filling rate of the number of vanes and the fluid transport efficiency of a single guide vane is independent of the total number of vanes.

叶片式推进剂罐沿平行叶片的流体传输的数值模拟

油箱是管理推进剂的卫星的核心组件。本研究数值分析了叶片型表面张力罐中平行导向叶片的流体传输。使用Flow3D在比例模型中模拟液体在微重力下的运输，液体填充率为15％，并与实验数据进行了比较。然后，使用这些模拟来比较各种工况下的前沿爬升速度和各种液体填充率，各种叶片数量的指定横截面以下的液体量。结果表明，在突然消除重力的作用下，板罐内导板上的液体爬升过程可分为液位重新定位阶段和稳定的流体输送阶段。在整个毛细管流动阶段，
