Abstract
The continued miniaturization and demand for improved performance of electronic devices has resulted in the need for transformative thermal management strategies. Microchannel flow boiling is an attractive approach for the thermal management of devices generating high heat fluxes. However, designing heat sinks for two-phase operation and predicting their performance is difficult because of, in part, a lack of experimentally validated physics-based flow boiling models and commonly encountered flow boiling instabilities. In this talk, I will discuss our work on the experimental validation of a numerical phase change model for microchannel flow boiling. I will also cover our ongoing efforts to characterize the effects of flow boiling instabilities on two-phase cooling performance under transient and non-uniform heating conditions.

Biography
Todd Kingston is a Ph.D. Candidate in the School of Mechanical Engineering at Purdue University and conducts research in the Cooling Technologies Research Center. Todd obtained a Bachelor of Science and Master of Science, both in Mechanical Engineering, from Iowa State University in 2011 and 2013, respectively. At Purdue, Todd is currently collaborating with the Naval Surface Warfare Center Crane Division to investigate the effects of transient and non-uniform heating on flow boiling instabilities in two-phase thermal management systems. Todd’s primary research interests are in energy transport and conversion, specifically those involving multiphase flows and heat transfer.
