What is it about?
Our paper reviews correlations that predict liquid film thickness in microchannels for gas-liquid and liquid-liquid flows. The variations of liquid film thickness are plotted over a wide range of capillary numbers for both experimental and computational studies. This study shows that the effects of the cross-sectional area on the flow patterns and flow characteristics have not been sufficiently investigated by researchers, particularly for rectangular cross-sectional areas with different aspect ratios.

Why is it important?
The two-phase Taylor flow has received considerable attention from researchers in recent decades due to its potential use in various industrial and medical applications. A large number of experimental, analytical, and numerical efforts have been taken by researchers to understand the fundamental characteristics of two-phase flows and the relevant transport phenomena. This paper presents a comprehensive review of the hydrodynamics, flow pattern, and liquid film thickness in two-phase flows through mini- and microchannels with different cross-sectional geometry.
Perspectives
I believe our review paper is a one-stop reading material for those who want to see a set of updated information on the field of Taylor flow. Preparing this paper was a great teamwork with my co-authors, so we must classify and figure out how to design different sections/subsections of the paper and present a lot of information logically.
