英文摘要: Abstract(#br)Induction time, an important factor in the adhesion process of mineral particles to bubble surfaces, has been determined only by experimental methods that are time consuming and expensive. This study aims to introduce a numerical approach to describe bubble–plate attachment by determining the induction time using smoothed particle hydrodynamics (SPH). Each subprocesses of bubble-plate attachment process including liquid film thinning, liquid film rupture, three-phase contact line extension, and stable three-phase contact line formation are distinguished by both qualitative images and four different specific kinetic energy profiles of simulation results. Most notably, numerical results indicated that our SPH model can successfully simulate a dynamic process of bubble–plate...
