Project Description

  • Nanoscale Thermal Transport

Interfacial thermal resistance (ITR) plays a crucial role in nano-scale device components and surrounding/confined fluid. The behaviors and reliability of such devices strongly depend on the way the systems dissipate heat, low ITR makes system possible to reduce heat losses. Hence, I investigate the ITR under the effects of nanodomains. I focus on thermal transport at Solid/Liquid interfaces, Crystal/melt interfaces, and Solid/Solid interfaces. Despite they all exhibit interfacial dissimilarities (e.g., atomic structures, states, vibrational frequencies, etc.), the thermal transport characteristics are different.

  • Nanoscale Fludic Transport

I perform atomistic simulations to observe the different physics between nanoflows and classical fluid transport theories. I also check the validity and limitations of the continuum hypothesis. At atomic-scales, the interface/surface forcefield becomes significant and highly affects the flow behaviors due to the very high-surface-to-volume-ratio. Density fluctuations (including peaks and valley) and apparent enhanced-viscosity are typically observed at such small scales. Therefore, the interface effects are treated via modified boundary conditions. Finally, the continuum-based modified-analytical solutions are suggested.
