Abstract： To clarify the working characteristics and propellant management capabilities of screen channel tanks during actual flight，a three-dimensional simulation model of a specific screen channel tank is established based on the volume of fluid model and the continuous surface tension model. The reorientation process of the tank is simulated under different filling rates and disturbance conditions. The distribution patterns of gas-liquid phases and the changes in the center of mass of the propellant during the reorientation process is examined，comparing the flow management capabilities of the screen channel tank with those of a vane-type tank. The results indicate that，in the face of varying filing rates and disturbance conditions， the screen channel tank exhibits greater liquid retention stability than the vane-type tank， particularly under a low filling rate of 5% ，where localized flow failure is less likely to occur. Under low filling conditions， the gas-liquid phase distribution during the reorientation process is primarily constrained by the surface tension of the screen channel structure. As the filling rate increases， the impact of external disturbances on the gas-liquid phase distribution during the reorientation process gradually intensifies，leading to an increase in the amplitude of center of mass oscilations. For initial conditions where the liquid phase is at the bottom，the screen channel tank responds most sensitively to reverse acceleration disturbances，while overcoming the efects of lateral acceleration disturbances is more challenging. This research provides a reference for the engineering application and design optimization of screen channel tanks in future aerospace missions.

空间环境下，在微重力、表面张力等弱力场作用下，推进剂贮箱内的气液分布极不稳定，很可能无法满足控压排气、发动机点火、在轨加注等任务对单相气体或液体推进剂的排放及输送需求。（剩余16125字）
