Abstract
During this investigation, we utilized the COMSOL software to simulate the motion of a hydrogen bubble in water. The simulations were executed within COMSOL, employing a direct numerical solver and electrochemistry models. We carefully chose an appropriate method for capturing the interface to monitor the evolving surface of a growing bubble. Among the options—level set, phase field, and moving mesh interface capturing methods—the study concluded that the moving mesh framework is optimal for simulating bubble growth. Additionally, the study emphasizes that effectively harnessing hydrogen as a transitional energy indicator could pave the way for alternative solutions, particularly in light of diminishing petroleum reserves, assuming a proficient mastery of production technologies.
