微尺度流动研究的简要综述

BRIEF SUMMARIZATION OF MICRO-SCALE FLOW RESEARCH

显微机械加工技术和微机电系统研究的发展为微尺度流动研究开辟一个全新的领域。微观尺度下表现出来的大表面积体积比、表面效应、稀薄性和可压缩性等问题,表明微尺度流体流动所基于的物理因素与宏观尺度下是不同的。目前,微尺度流体流动应用技术的发展速度已经远远超过其本身机理的研究,文中对微尺度流体流动的有关研究进行阐述,为其本身机理的进一步深入研究提供参考。

The development of micromachining technology and micro-electro-mechanical system(MEMS) opens up a new territory for the research of micro-scale fluid flow.It illustrates that basing physical factors of micro-scale fluid flow are different from those of macro-scale fluid flow because of the large surface-volume ratio,surface effects,rarefaction and compressibility.Now,the micro-scale fluid flow technology is progressing at a fast rate that exceeds its mechanism research.The primary objective is to review the...
