This is one of the major factors which causes the disagreements on the friction factor of microchannel flow in the literature; for the gaseous flow in the slip regime, an evident lower flow resistance is observed due to the gas rarefaction effect which causes.
实验结果表明,即使在较小的相对粗糙度高度下,由于微通道中的粗糙度分布密集,会极大地增加流动阻力,这是导致文献中微通道流动阻力系数实验值相互偏差的主要原因之一;而对于滑移区的气体流动,气体稀薄性使流动阻力明显减小而导致流量增加。
