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.

主要研究人员建议进行一系列实验，以研究微米级通道中的换热和流体流动。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。这项研究将使用各种气体。实验的目的是确定表面粗糙度、流道几何形状和稀薄程度对摩擦因数和换热性能的影响。
