TL;DR: In this paper, the authors measured the two-phase pressure drop in Taylor slug flow in a capillary and found that if the slug length was smaller than 10 times the capillary diameter, the length-averaged friction factor increased drastically from the single phase value (f = 16/Re) due to differences in curvature at the front and the back of the bubble.

TL;DR: In this paper, the authors present transient measurements of the flow field during the formation of bubbles in a microfluidic T-junction using microscopic particle image velocimetry (PIV).

TL;DR: A closed-form expression that allows the reader to predict the size of bubbles and droplets created in T-junctions without fitting is presented and teaches how the shape can be tuned to obtain the desired size.

TL;DR: In this article, an extensive analysis of the performance of the volume of fluid (VOF) method, as implemented in OpenFOAM, in modeling the flow of confined bubbles and droplets (segmented flows) in microfluidics is provided.

TL;DR: Direct time-resolved imaging of melt pool flow dynamics from a high-energy synchrotron radiation experiment is presented to show surface tension affects flow speed, orientation and surface turbulence.
