Gas bubble dynamics
Dominique Legendre, Roberto Zenit
Abstract
The motion of gas bubbles in liquids plays a vital role in numerous natural, industrial, and everyday phenomena. Unlike solid particles, gas bubbles are nearly weightless and highly responsive to forces from the surrounding fluid. Their dynamics are affected by added mass acceleration and deformable surfaces, and also by interactions with turbulent flows, other bubbles, and walls, with liquid rheology and surfactants further influencing their behavior. This review examines the intricate behavior of noncondensable gas bubbles, highlighting key advances over the past 20 years. Key topics include turbulence, non-Newtonian fluids, and electrolytes, offering insights to enhance modeling and guide future research in two-phase flow systems.
