MEMS Seminar: Scalable Manufactured Micro/Nan-Structured Surfaces for Heat Transfer Applications
Wednesday, May 24, 2017
12:00 pm - 1:00 pm
Professor Ronggui Yang
Thermal transport plays an important role in energy conversion efficiency and device reliability. There were significant progresses over the past 2 decades on utilizing micro/nanostructures for enhancing or reducing heat transfer owing much to the challenging needs in high efficiency energy conversion and thermal management of electronics. One of the great examples is to use nanostructures for enhancing the efficiency of thermoelectric materials by reducing the thermal conductivity. Yet, cost-effectiveness plays a key role in engineering micro/nanostructures for heat transfer applications. In this talk, I will highlight two examples that we currently work on by utilizing scalable manufactured micro/nanostructured surfaces for enhancing heat transfer processes: phase-change heat transfer and radiative heat transfer. These surfaces are expected to play an important role in future thermal and energy system
