(2011-02-08)n fluid dynamics, slosh refers to the movement of liquid inside a hollow object. We examine these dynamics in a scale-model of the Orion Service Module (SM) down-stream hydrazine propellant tank. The SM is a component of ...
Investigation of Propellant Sloshing and Zero Gravity Equilibrium for the Orion Service Module Propellant Tanks(2012-08-09)We study fluid slosh in the Orion Service Module propellant tanks. Resonant slosh frequencies were measured as a function of tank fill-fraction in a scaled model of the tanks. We carry out both computational and theoretical ...
(2011-02-08)Air cyclones are a promising technology for first stage air filtration in future lunar habitats where lunar dust mitigation is a mission critical concern. Our experimental work with cyclones in microgravity as part of ...
