FLOW REGIMES IN MICROCHANNEL SINGLE-PHASE GASEOUS FLUID FLOW

摘要

As the market induces electronic chips to undergo a size reduction while increasing functionality, the use of convective heat transfer in microchannels is believed to be one of the most efficient ways to provide the necessary cooling. Many analytical and experimental investigations have been performed to provide a better understanding of liquid and gaseous flow and heat transfer at microscale, which is very important in microdevice development and design. However, these studies have yet to lead to a general conclusion. Controversial results in the literature about the boundary conditions for liquid flows show that further investigations are still needed.
