“…They addressed the droplet deformation at the turns, which contributes to the mixing process. Fries and von Rohr [34] investigated the mixing process in slugs and found that the mixing length could be decreased to 12% compared to that in the straight channel design.…”

“…Numerical investigations on flow field or mixing in droplets moving in straight [35][36][37] or meandering microchannels [34,38,39] have been reported. Some simulations were carried out with interface prediction methods to capture interface shapes [33,[37][38][39], while others assumed flat or curved interface shapes [34][35][36].…”

“…The ratio of film and cap mass transfer is an important parameter in determining if inter-phase mass transport can be improved through redistribution of cap and film area via bubble breakup and flow pattern transitions (Kirpalani et al, 2008;Fries and von Rohr, 2009;Donaldson et al, 2010). In the CFD simulations of van Baten and Krishna (2004), film mass transfer typically accounted for 60% of the overall transfer between the bubble and liquid slug.…”

“…A horizontal xy plate vortex is also apparent if the channel cross section is square, due to the drag from the side walls. Researchers have used particle image velocimetry and other methods to image the described pattern in the specialized case of slug flow, where the droplet completely fills the channel [King, Walsh, and Grimes, 2007;Kashid et al, 2011;Fries and von Rohr, 2009;Sarrazin et al, 2008]. Simulations of confined cases have also been performed [King, Walsh, and Grimes, 2007;Kashid et al, 2011;Fries and von Rohr, 2009;Sarrazin et al, 2008].…”
