Abstract
*† ‡ § Control of cryogenic propellant tank pressure during tank refueling and expulsion in low gravity is an important technical challenge to overcome for future long duration missions or an orbiting fuel depot. One method proposed to control tank pressurization involves the use of jet-induced geysers. A computational simulation was enhanced with a k-ω turbulence model and used to investigate jet-induced geyser formation in reduced gravity. The enhanced model is subsequently validated and compared to experiment data obtained by other investigators. The effects of spread rate and the influence of contact angle were evaluated with respect to dimensionless geyser height. The results affirm that the current version of the simulation using the k-e turbulence model provide the most accurate results for jet-induced geysers in reduced gravity when compared to available experiment data.
