Effects Of Micro-Gravity On Thin-Wire Subcooled Nucleate Boiling Dynamics, Troy Munro, Andrew Fassmann

Posters

Nucleate boiling is a highly effective means of transferring heat, and as space exploration begins to reach farther from Earth, efficient heat management systems in microgravity are becoming increasingly important. In the summer of 2010, members of the USU Get Away Special (GAS) team flew aboard NASA’s Weightless Wonder in order to study the effect of various system parameters on nucleate boiling heat transfer behavior in microgravity. This one dimensional study of boiling used a new geometry never tried before and concluded that heat transfer rates during boiling in microgravity do not significantly differ from those observed on Earth. These …

Development Of Optimal Bubble-Seeding Microheaters To Study Nucleate Boiling Heat Transfer In Microgravity, Ryan Martineau, Iggy Matheson, Landon Hillyard

Heat management is a critical issue facing engineers of spaceflight systems. Nucleate boiling has high heat transfer rates, but further study is needed to apply this method effectively to a heat transfer system in a microgravity environment. The USU Get Away Special (GAS) team is conducting a series of experiments aboard NASA's "Weightless Wonder" aircraft to further understanding of nucleate boiling activity in microgravity. Two specific focuses of the current experiment are determining optimal surface geometries of microheater arrays designed to induce nucleate boiling and constructing a lighting and video system to spatially and temporally resolve the anticipated jets of …

A Systemic Study Of Nucleate Boiling, Justin Koeln

Posters

Nucleate boiling is a heavily researched form of heat transfer due to its associated high heat transfer rates. Applying two-phase heat transfer to space systems would allow these systems to become more capable, efficient, and compact. However, a fundamental understanding of boiling dynamics in the absence of buoyancy is yet to be developed. This study intends to analyze the effects of gravity, power input, and surface geometry during successive periods of microgravity provided by NASA’s “vomit comet” through the Reduced Gravity Student Flight Opportunities Program.

Funboe - Follow-Up Nucleate Boiling On-Flight Experiment: A Systematic Study Of Nucleate Boiling In Microgravity, Jt Farnsworth, Frank Mccown

Posters

Utah State University’s Get Away Special (GAS) team was awarded the opportunity to participate in Reduced Gravity Student Flight Opportunities program administered by NASA. Six members of the GAS team will fly in a specialized jet which will simulate microgravity where the experiment can be performed in 30 second intervals. The purpose of the experiment is to determine the properties of nucleate boiling of water in weightlessness. The experiment will be monitored with temperature sensors, accelerometers, and high definition cameras and the results will be analyzed frame by frame. This will provide important information related to the dynamics of heat …

Space Research Projects For The International Space Station, Kyle Hodgson

Space Italian Dressing Experimental Setup (SIDES) examines the dynamics of fluid segregation between fluids of differing densities. While in space the fluids will not undergo buoyant or convective forces, thus isolating the affects of separation due to density and molecular forces. The experiment will serve as an outreach experiment in addition to gleaning scientific data; mixtures are a topic of study in the 5th grade curriculum.

The objective of International Paper Airplanes in Space (IPAS) is to excite children about space research by giving them a chance to take part in it. IPAS includes collecting paper airplanes made by elementary-school …

Photoelectric Charging By Ultraviolet Light Of A Lunar Dust Simulant In A Microgravity Environment, Troy Munro, Andrew Fassmann

Posters

A microgravity experiment to test the electrostatic behavior of a lunar dust simulant being charged through the photoelectric effect will expand understanding of the charging characteristics of dust particles and may lead to a possible mitigation solution. With a design based upon Robert Millikan’s oil-drop experiment, this experiment is designed to observe the interactions of a lunar dust simulant without the conflicting effect of a dominant gravitational force. The dust particles will be charged by means of a lamp capable of photon energies necessary to emit electrons by the photoelectric effect. In the presence of an axial electric field, the …
