Phase Change in High-Density Confined Liquids for Thermal Management

Abstract

The proposed research comprises of three main tasks which involve water, dielectric coolants and glycols/alcohols as the working fluids: 1. Estimation of heat transfer related properties of water confined in nanochannels 2. Visualization, thermal characterization and modeling ofbubble formation in water confined in nanochannels 3. Visualization and experimental heat transfer analysis of bubble formation in confined dielectric coolants as well as glycols/alcohols. In addition to nucleation experiments and simulations, we are also utilizing wicking in suchnanochannels to estimate the disjoining pressure in experiments with validation from theory and CFD, followed by implementing those pressure values in CFD simulations and modeling the bubble nucleation process. Further, we have utilized a novel design of buried channels with micropores to estimate the heat flux capability and vapor velocity from the menisci in such channels.
