Slosh wave excitation associated with high frequency impulsive reverse gravity acceleration of geyser initiation
Abstract
The objective of the cryogenic fluid management of the spacecraft propulsion system is to develop the technology necessary for acquisition or positioning of liquid and vapor within a tank in reduced gravity to enable liquid outflow or vapor venting. The requirement to settle or to position liquid fuel over the outlet end of spacecraft propellant tank prior to main engine restart poses a microgravity fluid behavior problem. The purpose of this study is to investigate the stability of the most efficient technique for propellant resettling through the minimization of propellant usage and weight penalties. In this study slosh wave excitation induced by the resettling flowfield activated by 10-Hz high-frequency impulsive reverse gravity acceleration during the course of liquid fluid reorientation with the initiation of geyser for liquid filled levels of 30, 50, 65, 70 and 80 percent have been studied. Characteristics of slosh waves with various frequencies excited are discussed.
