Advanced Transport Technologies for NASA Thermal Management/Control Sytems University of Nevada, Reno, NASA Glenn Research Center, Space Technology Mission Directorate

Thermal management of NASA life-support, high-power electronics, and measurement systems enables a wide variety of crucial space, air-flight, and monitoring technologies. These systems employ fluids to cool heat-generating modules and efficiently transport that energy to components for utilization or rejection to space. Current heat exchangers at the interfaces between the thermal management system and these components rely on single-phase convection. As a result, these heat exchangers are relatively large and heavy. Augmented single-phase and phasechange (in which the fluid boils and/or condenses) heat exchangers hold promise to reduce the size and enhance the performance of these systems, if reliability issues can be resolved. A highly-integrated, statewide research and educational advancement program will be conducted among four Nevada System of Higher Education (NSHE) institutions: the University of Nevada, Reno (UNR), the University of Nevada, Las Vegas (UNLV), Truckee Meadows Community College (TMCC), and the Desert Research Institute (DRI). The program objective is to develop advanced single-phase and phase-change loop heat transfer technologies that will enhance the performance and reliability of the NASA thermal management/control system. In addition, this work will be the basis for the development of innovative and interactive educational modules as well as technology transfer. The proposed work will fund four faculty members and four Ph.D. students who will gain experience in areas of interest to NASA.
