Validation of Propellant Dynamics Model
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 ...
Measurements of the Collection Efficiency of an Air Cyclone in Lunar Gravity
(Wisconsin Space Grant Consortium, 2009-03-15)
We report experimental results on the collection efficiency of an air cyclone operating with a lunar dust simulant under lunar gravity. Microgravity collection efficiency is, to within experimental uncertainty, not different ...
Repose Behavior of Lunar Regolith Simulants
2008 Test Equipment Data Package (TEDP)
2011 Carthage Microgravity TEDP
Computational Fluid Dynamics Model of a Cyclone Separator
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 ...
The Young’s Modulus of Single-Walled Carbon Nanotubes
Carbon nanotubes (CNTs) were discovered in 1952, but their exciting properties have been brought to the attention of the scientific community only recently. CNTs, which can be thought of as rolled up sheets of graphene, ...
Modal evaluation of fluid volume in spacecraft propellant tanks
A novel, real-time method of determining the volume of propellant present in a spacecraft tank in reduced gravity is presented. In the experiment reported here, modal analysis techniques are applied to detect shifts in ...
