Abstract—A numerical study dedicated to observe bubble detachment phenomena from solid wall has been carried out. The Comsol Multiphysics’s level set method has been chosen to perform numerical simulations. Numerical results are clearly evidencing bubble detachment and formation of jet inside detached bubble, which after deforming bubble maneuver inside with relatively higher velocity. Detachment time is found to be a direct function of bubble size and shows linear behavior for various fluids. Detailed study reveals that there exists a bubble size effect on jet formation.
