Experiments on Gaseous Flow in Micro Channels

摘要：主要研究人员提出了一系列实验来研究微米尺寸通道内的传热和流体流动。微通道将在位于主要研究机构的薄膜和界面研究中心制造。实验所需的微型压力和温度传感器也将由同一设施制造。研究中将使用各种气体。实验旨在确定表面粗糙度、通道几何形状和稀薄度对摩擦系数和传热性能的影响。

ABSTRACT The principal investigators propose to conduct a series of experiments to study heat transfer and fluid flow in channels that are of micrometer dimensions. Micro channels will be fabricated at the Center for Thin Film and Interface Research located at the principal investigators' institution. Microscale pressure and temperature sensors that are required for the experiments will be also be fabricated by the same facility. Various gases will be used in the study. The experiments are designed to determine the effects of surface roughness, channel geometry, and rarefication on the friction factor and heat transfer performance.
