Simulation of coalescence, break up and mass transfer in bubble columns by using the Conditional Quadrature Method of Moments in OpenFOAM [PDF]
, 2013 The evaluation of the mass transfer rates and the fluid-dynamics aspects of bubble columns are strongly affected by the intrinsic poly-dispersity of the gas phase, namely the different dispersed bubbles are usually distributed over a certain range of ...

Effect of Electrolyte Concentration on Bubble Size and Gas-Liquid Interfacial Area in Bubble Column
Tikrit Journal of Engineering Sciences, 2005 The optimum conditions of bubble column would be the ones that enhance mass transfer and this is accomplished by maximizing gas-liquid interfacial area. In the present work the effect of electrolyte concentration (aqueous solution of sodium chloride NaCl

An investigation on chemical bubble column using ultrasonic tomography for imaging of gas profiles [PDF]
, 2014 In this paper, we carried out a tomographic investigation of a chemical bubble column using ultrasonic sensor. The ultrasonic tomography sensing array was constructed to operate in transceiver-mode and was clamped on the exterior circumference of the ...

Advanced Functional Materials, EarlyView.By tuning the pore size of mesoporous N‐doped carbon (MPNC) nanospheres as support material for molybdenum sulfide, the electrochemical activity of the composite material for the hydrogen evolution reaction can be optimized. An ideal MPNC pore size of 60 nm allows a high number of molybdenum sulfide active sites while maintaining efficient proton and ...

On the scale-up criteria for bubble columns
Petroleum, 2019 It is generally admitted that experimental data obtained in “laboratory-scale” bubble columns are representative of “industrial-scale” reactors if the well-known three “Wilkinson et al.
