Flow patterns and slug scaling of liquid-liquid flow in square microchannels
, 2019 Liquid-liquid flow regimes in three square microchannels were visualized simultaneously both at the cross-shaped junction and in the microchannel “far” from the junction in order to reveal flow regime evolutions along the microchannel.

Advanced Science, EarlyView.An exogenous reagent‐free dual‐substrate strategy harnesses phenol as an intrinsic electron donor to drive synchronous phenol degradation and Cr(VI) reduction over modified carbon nitride. π–π stacking and hydrogen bonding direct electron transfer to the catalyst, enriching photogenerated electrons and accelerating Cr(VI) reduction 6.4‐fold. This waste‐

Numerical Modelling of Gas-Liquid Slug Flow Regime with a Conservative Two-Fluid Model Using the Shock Capturing Method [PDF]
Iranian Journal of Chemistry & Chemical EngineeringAn approach for simulating the initiation of slugs in horizontal pipes is proposed in this research. An analogy is established between the algorithms for solving single-phase problems with discontinuity (Riemann problems) and two-phase slug flow (having ...
