A predictive model for bubble-particle collisions in turbulence
Timothy T. K. Chan, Linfeng Jiang, Dominik Krug
The modelling of bubble-particle collisions is crucial to improving the efficiency of industrial processes such as froth flotation. Although such systems usually have turbulent flo…
To jump or not to jump: Adhesion and viscous dissipation dictate the detachment of coalescing wall-attached bubbles
Çayan Demirkır, Rui Yang, Aleksandr Bashkatov +3
Bubble coalescence can promote bubble departure at much smaller sizes compared to buoyancy. This can critically enhance the efficiency of gas-evolving electrochemical processes, su…
The effect of gravity on bubble-particle collisions in turbulence
Timothy T. K. Chan, Linfeng Jiang, Dominik Krug
Bubble-particle collisions in turbulence are key to the froth flotation process that is widely employed industrially to separate hydrophobic from hydrophilic materials. In our prev…
Electrolyte spraying within H bubbles during water electrolysis
Aleksandr Bashkatov, Florian Bürkle, Çayan Demirkır +10
Electrolytically generated gas bubbles can significantly hamper the overall electrolysis efficiency. Therefore it is crucial to understand their dynamics in order to optimise water…
