| Abstract: | Hydrodynamics and mass transfers are discussed both within the dimpled liquid film and along the gas liquid interface between two bubbles, and a model of coalescence is developed, in which the effects of London-van der Waals forces and electric double layer forces are taken into account.The predicted results of the present model match previous experimental data well. |
