Abstract:
The high heat transfer rates associated with boiling is attractive for increasing the thermodynamic efficiency of extracting energy from solar, fossil, and nuclear fuels in the power industry. Boiling is also essential in numerous technologies such as thermal management of microelectronics, refrigeration cycles, modern chemical and distillation processes. Notably, the boiling heat transfer coefficient depends on the applied heat flux. The maximum heat transfer coefficient occurs prior to the critical heat flux limit, concurrent with the highest active nucleation site density. I this seminar, I will discuss the use of spatial confinement as a technique to enhance the heat transfer in conditions where conventional pool boiling results in low active nucleation site density. I will demonstrate the impact of the confinment on the two-phase interface dynamics associated with boiling. Then, on the second part of this talk, I will focus on leveraging this deep mechanistic understanding of the confinement effect to develop a predictive model of the thermal behavior of confined boiling which will enable a wider practical systems implementation of the technique.
