Experimental and Theoretical Study of Transport Phenomena in Micro-Channel Heat Sinks
We investigate into the transport phenomena of flow boiling in micro-channel heat sinks in two-phase cooling and refrigeration loops. The relation between two-phase flow and its heat transfer mechanisms in micro-channel heat sinks has not been fully understood by its complex characteristics those appear as several phenomena are coupled together such as instability induced periodic flows, flow oscillations and following dry out, and heat transfer dependence on transient flow patterns. Flow visualization techniques; high-speed imaging, IR-thermography, and stereo PIV, and accurate measurement techniques have been employed for experimental verification in conjunction with theoretical and computational endeavors. Results can be applied to cooling of electric vehicle(EV), battery and electronics, and avionics.
