“…The Knudsen minimum through the channels via sudden contraction or expansion was observed by Sazhin [142] and Gavasane et al [143]. In the former work, rarefied gas flow through a vacuum in long and short rectangular channels with sudden contraction or expansion in cross-section was investigated using the DSMC method.…”

In today’s complex micro–electro–mechanical systems (MEMS), investigation of flow through irregular micro/nanochannels, such as bended channels, variable cross-sectional area channels, and those with rough surfaces, can contribute considerably to efficient designing of the microdevices and to gain a better understanding of the flow structure in these geometries. The present paper reviews the prominent studies published in literature on rarefied gas flow through these types of complex geometries. The main focus of the study is to explore the physical aspects of the findings and the analyses provided in support of the results. Finally, the areas in which a gap exists in literature and could be subjects of future studies are introduced.
