摘要: A key objective of the cryogenic fluid management spacecraft propulsion system is to develop technology necessary for acquisition or positioning liquid and vapor within a tank in reduced gravity enable outflow venting. The requirement settle position fuel over outlet end propellant before main engine restart poses microgravity behavior problem. Resettlement reorientation can be accomplished by providing optimal acceleration such that reoriented outlet. In this study slosh wave excitation induced resettling flowfield during course with initiation geyser liquid-filled levels 30, 50,65,70, 80970 have been studied. Characteristics waves various frequencies excited are discussed. Slosh excitations will affect stress distribution exerted on container wall shift mass inside container, which imposes time-dependent variations moment inertia container. This information important control reorientation.
