讲座摘要:Two-phase transport is promising in addressing the cooling challenges facing high power microelectronics. However, it is extremely challenging owing to the fact that two-phase transport performance is primarily governed and also limited by the detrimental aspects of complex two-phase flow in conventional channels. Two-phase transport at micro/nanoscale becomes more unpredictable due to the unfavorable size effect. Over the past several decade, extensive progress has been made in understanding two-phase transport on various microchannel designs and configurations. Driven by the intrinsic scientific interest and needs of emerging applications, it is highly desirable to realize a favorable control of complex two-phase flows and then heat transfer in microchannels.
Most recently, Dr. Li’s group has devised several novel micro/nanoscale fluidic control methods. Through designing novel micro/nanoscale structures, these methods can (a) passively generate sustainable and on-demanding mixing in the laminar flow regime in microchannels, and (b) intentionally reduce transitional two-phase flow regimes into a single and favorable flow regime for better heat transfer performance and flow characteristics. Drastic enhancements have been demonstrated without compromise. In this talk, Dr. Li will give a brief of his research program and share his recent progresses in understanding micro/nanoscale fluidic control methods developed in his research.
