ABSTRACT
Abstract Interaction of air bubbles with solid surfaces is important in many chemical engineering applications with mass and heat transfer, and separation processes. This review focuses on the collision and attachment interactions between a rising bubble and a flat surface in water and surfactant solutions. The analysis involves a numbers of important aspects of the bubble motion and contact interactions which are governed by both long-range and short-range (thin film) hydrodynamics of the bubble rise, surfactant adsorption and desorption, wetting film drainage and rupture, and spreading and relaxation of three-phase contact lines. Featured properties of air-water interface deformation, interfacial forces produced by adsorbed surfactants and interfacial mobility have a significant influence on the attachment and dewetting interactions.
