Abstract: This paper studies the volume of a fluid model in order to simulate bubble bursting at free surface. Transient conservation equations of mass and momentum with consideration of tension and gravitational force effects were solved. The simulation results of bubble rising at stagnant liquid were validated with numerical and experimental results of literature where the agreement was good. A single-gas bubble with constant density and viscosity was released in stagnant liquid to reach the free surface of the gas properties and bursting. The simulations were preformed in a two-dimensional Cartesian coordinate system and indicated that the volume of the fluid method is an appropriate approach in order to simulate collapsing bubbles at free surfaces. However, the volume of fluid technique could be developed to increase bubble behavior at free surfaces.
