eng Abstract:
Surfactants profoundly alter the hydrodynamics of gas-liquid interfaces in multiphase industrial processes (e.g., flotation, bioreactors). This study investigates the impact of non-ionic surfactants on the rise velocity and surface mobility of isolated bubbles in a stagnant liquid. The accumulation\nof surfactant molecules at the interface induces Marangoni stresses, shifting the boundary condition from fully mobile (free-slip) to rigid (no-slip)1.\n Host item entry: Proceedings Abstracts, ISBN 978-80-86186-36-8
