A model of bubble growth in wetting and non-wetting liquids

Effect of Tween 80 on Bubble Size and Mass Transfer in a Bubble Contactor

“…Nevertheless, whilst the impact of the liquid density and viscosity was extensively studied, the liquid surface tension and its effects must be analyzed in gas-liquid contactors. Taking into account the results and conclusions concerning the effect of the liquid surface tension, its influence is not clearly separated from the effect caused by density and viscosity [1,2].…”

Numerical simulation of bubble formation on orifice plates with a moving contact line

“…The traditional predictions based on the force balance at a certain time point are barely successful (Fritz, 1935;Jensen and Memmel, 1986). 2 Most of the numerical simulations on gas bubble formation on submerged orifices were carried out either using non-spherical models (interfacial element method) (Marmur and Rubin, 1976;Liow and Gray, 1988) or using rigorous boundary integral methods (Oguz and Prosperetti, 1993;Xiao and Tan, 2005). The latter is applicable only to a restricted type of flow problems, e.g., potential or Stokes flows.…”

“…Very few studies are available by solving the full Navier-Stokes equations, e.g., Gelach et al (2007), perhaps due to the high computational costs. Only a few numerical studies have taken into account the effects of moving contact line, e.g., Liow and Gray (1988). In the study of Gelach et al (2007), a constant contact angle was used to study the effects of wettability.…”

Influence of liquid surface tension (surfactants) on bubble formation at rigid and flexible orifices

“…In the works where the liquid surface tension is considered, its influence is not really separated from those of liquid density and viscosity [14][15] and they are limited to the use of organic liquids. In particular, the effect of surfactants on the bubble formation phenomena remain a scientific area virtually unexplored in spite of its practical and industrial value [16][17].…”
