Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Power generation through heat to electrical energy conversion for space applications faces distinct challenges not encountered in terrestrial settings, where Rankine and Brayton cycles have traditionally been predominant. The unique environment of space necessitates the adoption of either static converters, leveraging solid-state physics, or closed-cycle dynamic converters. While thermoelectric generators have historically been the primary choice for heat-to-electrical energy conversion in space applications, their relatively low efficiencies and limited scope for enhancement pose significant challenges as the power demands of space missions increase. This necessitates the exploration of alternative power generation methodologies to meet the evolving requirements. This thesis provides a comprehensive analysis of various power conversion technologies for space applications, focusing on the comparative study of static and dynamic converters, with a particular emphasis on Stirling converters. Other power systems discussed include thermoelectric, thermophotovoltaic, thermionic, and Brayton converters. Through comparative analysis, the research identifies the most promising converters for future space applications.
