Dynamics of an isolated bubble injected at the horizontal wall in a shear flow

Growth of bubbles nucleated on a wall appear in various industrial applications (gas/liquid contactors, evaporators, hydrogen production), in which their detachment radius is an important parameter for performance optimization. Thanks to gas injection experiments in a shear flow, a force balance model for predicting the detachment radius is built using the relevant forms of the forces extracted from recent literature. A new detachment criterion, based on a maximum advancing contact, allows to determine the receding contact angle and detachment radius with good agreement for both hydrophilic and hydrophobic surfaces.
