"Bubbles in electrolysis" by Dominik Krug, Institute of Aerodynamics and Chair of Fluid Mechanics, RWTH Aachen University

Published on November 10, 2026 – Updated on November 10, 2026

Dominik Krug, from the Institute of Aerodynamics and Chair of Fluid Mechanics at RWTH Aachen University, will give a seminar exploring one of his research topics: “Bubbles in Electrolysis”. His research examines gas bubbles forming on electrodes and their impact on the efficiency of water electrolysis. Experiments with micro-electrodes and transparent electrodes investigate bubble dynamics and the conditions under which bubbles detach. The work considers Marangoni convection, contact line motion and bubble coalescence, as well as the role of adhesion energy and viscous dissipation. It aims to better understand the mechanisms governing bubble departure and to establish physics-based criteria for predicting it.
