Opis

Thermal transport in microchannels is investigated tobetter understand the fundamentals of single-phaseconvection and flow boiling at the microscale.Measurements of single-phase pressure drop and heattransfer suggest that conventional Navier-Stokestheory and carefully selected correlations developedat larger scales are entirely capable of predictingsingle-phase transportcharacteristics in the microchannels. Bothcomputational fluid dynamics analysis and approximateanalytical models are then presented to study themicroscale convection-conduction conjugate problemand to aid in the practical design and optimizationof microchannel heat sinks. Convective flow boilingin microchannels is also experimentallycharacterized. Analytical models are developed topredict the onset of nucleate boiling and convectiveboiling heat transfer coefficients in microchannelsover a wide range of flow conditions. In addition, anon-intrusive diagnostic technique, infraredmicro-particle image velocimetry, is developed tofacilitate the measurement of flow fields withinsilicon-based MEMS devices with micron-scale resolution.
