Mesoregime-Oriented Investigation of Flow Regime Transition in Bubble Columns

Abstract: This work investigates regime transition in bubble columns through a mesoscale framework. The dominant mechanisms in bubble columns are analyzed according to the concept of mesoregime. Model predictions with the modified stability condition agree well with experimental data. It indicates a scenario of the regime transition. That is, the homogeneous regime is liquid-dominated, which is characterized by the dominance of liquid over the movement of small bubbles, while the heterogeneous regime is gas-dominated, w… Show more

“…Liu et al 7 prepared UF/polyacrylate molding compounds, and the impact strength was improved by 18% at 10 wt% polyacrylate compared with that of the neat sample. Han et al 8 studied the mechanical properties of polyethylene glycol toughened UF resin, and 16% improvement in impact strength was obtained for UF with 3 wt% polyethylene glycol. Also, in our previous study, polyurethane elastomers were chemically introduced into UF resin via in situ polymerization, and the toughness of UF resin can be clearly improved.…”
