In the microgravity environment, the position of the ullage bubble is uncertain. It's hard to vent and control the center of mass for the receiver tank on mission of onor-bit refilling. The test tank of FARE II is taken as reference. using theory of the surface tension tank and the method of numerical simulation, the on-orbit refilling performance of the vane surface tension tank was studied. Calculation...
Gas-liquid separation technology is a key part for such propellant resupply on orbit because of the microgravity condition. A new gas-liquid separation device used a simple spiral pipe is designed to provide gas-free propellant to the receiver tank. The two-phase flow in spiral pipe is simulated to study the effect of different inflow velocities on its separation performance using certain commercial...
