Simulations of Particle-Laden Flows with Large Dispersed-Phase Size Disparities Using Highly Scalable Parallel Adaptive Methods
Linfeng Jiang, Enrico Calzavarini, Dominik Krug
The numerical simulation of multiphase flows involving dispersed components with large scale disparities, such as the collisions between millimeter-sized bubbles and micron-sized m…
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…
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…
How turbulence increases the bubble-particle collision rate
Linfeng Jiang, Dominik Krug
We study the effect of turbulence on collisions between a finite-size bubble and small inertial particles based on interface-resolved simulations. Our results show that the interac…
