Title: Thermal dissipation at extremes using confined evaporating liquid films with streaming gas/vapor flows
Abstract: I will present recent advances in fundamental understanding of ultra-thin liquid film evaporation subjected to high velocity streaming gas/vapor flow, which allows for simultaneous reduction of convective/conductive heat transfer resistance across the liquid film and rapid removal of vapor from an evaporating liquid interface. This unique environment for observing evaporative heat and mass transfer dynamics is enabled by use of two complimentary thermal management schemes and testbeds: (1) ultra-small (<10 um) microgaps, with and without pin fins, for convective boiling in confined quasi-2D domains, and (2) nanoelectrospray impingement for controlled topology (<1 um) liquid film formation coupled to an entrained gas jet. The test sections are batch micromachined in silicon and instrumented with thin-film resistive thermometry to enable quantitative assessment of the capability for dissipating extreme heat fluxes up to multiple kW/cm2. These experimental systems and test parameters constitute extreme values in terms of geometry, film thickness, mass fluxes, and heat fluxes. New flow regimes for convective flow boiling and thin film evaporation will be identified and discussed, as a function of increasing heat flux and film confinement. Dominant mechanism(s) of two-phase heat transfer responsible for each regime are postulated based first principle heat/mass transfer modeling and flow visualization correlated with pressure drop, mass flux and thermal resistance measurements.

Title: MEMS sensor for cooling loss study of IC engine
Abstract:

Mitigation of cooling loss from the internal combustion engines is important target for improving the thermal efficiency. Heat loss mechanism has been unclarified yet, so new thin film type RTD surface temperature sensor was introduced to a comprehensive engine research in the SIP, Strategic Innovation Promotion Program by the cabinet office of Japan. The instantaneous and local heat flux was measured with a good signal to noise ratio by measuring surface temperature at 100 kHz rate by the RTD sensor and analyzing the transient thermal conduction inside the wall. The measured trends show that heat flux of a few hundred kW/m2 level was observed in the compression phase near the TDC, a jump up to several MW/m2 at frame front arrival to the inner wall surface in the combustion phase, and decay with a few millisecond level time constant in the expansion phase. It was also proposed that flow information near the wall was extracted by the correlation analysis among three heat flux fluctuation trends measured by an adjacent three point RTD sensor. Flow velocity parallel to the wall and a scale of hot or cold fluid bodies were statistically derived from a continuous 200 cycle heat flux data taken in the engine. The MEMS sensor applied to the harsh environment showed the fine results on the detailed heat transfer.
