Characterization and Model Validation of
Thermal and Flow Dynamics During Microchannel Flow Boiling
About the Presentation
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.
