Experimental investigation of annular two-phase flow splitting at a microimpacting T-junction

Experimental investigation of gas-liquid separation with a new combined impacting junction

“…Furthermore, under all tested conditions, phase redistribution was not affected by viscous forces. In comparison with the results of Azzopardi et al (1986a) with hydraulic diameter of 31.8-mm (macro-channel) and Elazhary and Soliman (2012) with hydraulic diameter of 3.4-mm (mini-channel), Chen et al (2014) phase redistribution was less severe with their testsection of 0.5 mm × 0.5 mm micro-channel. Chen et al (2015) used the same experimental set-up as Chen et al (2014).…”

Chen et al (2015) used the same experimental set-up as Chen et al (2014). The gas and liquid inlet superficial velocities were varied from 0.36 to 2.4 m/s and 0.1 to 0.9 m/s, respectively, which corresponded to slug flow regime.…”

Split of two-phase plug flow with elongated bubbles at a microscale branching T-junction

“…Thus, the behavior of the plug flows at the branching T-junctions (Ménétrier-Deremble and Tabeling, 2006;Azzi et al, 2010;Hong et al, 2010;He et al, 2011;Wolden, 2012;Chen et al, 2012Chen et al, , 2013Wang et al, 2014) or at the impacting T-junctions (Link et al, 2004;Jullien et al, 2009;Leshansky and Pismen, 2009;Fu et al, 2011;Afkhami et al, 2011;Hoang et al, 2013;Bedram and Moosavi, 2013;Samie et al, 2013) could be well predicted by analyzing the dynamics of the unit cell, provided that the distance between the bubbles (or the length of the liquid slugs) is long enough to avoid mutual interaction between them. Here, the branching T-junction implies a straight channel with a perpendicular side arm, whereas the impacting T-junction has two downstream channels both perpendicular to the upstream channel but pointing out in opposite directions from each other (Chen et al, 2014). In the branching T-junction, the upstream and downstream parts of the straight channel and the side arm are termed to be the main, run and the branch, respectively.…”

Cellulose through the Lens of Microfluidics: A Review

“…Following the evaporation of the water within the droplets, the molecular cross-linking of surface modified CNCs is accelerated. On the other hand, on a microfluidic chip, emulsification can occur through three broad designs of co-flow, fluid-focused flow, or the T-or Y-junction meeting of multiple flows [89,[92][93][94][95]. For instance, in Liu et al [96], a simple and novel approach was used to effectively create monodisperse ethyl cellulose hollow microcapsules.…”
