Abstract

In this paper, computational fluid dynamics modeling techniques to simulate the bubble bursting process and its ability to simulate the production of droplets for different bubble sizes are presented. A closed chamber is filled with fluid and air with the presence of bubbles in the fluid. The rising bubble eventually floats on the free surface forming a thin cap with a typical thickness of the order of 1 µm. To track the bubble cap, the mesh size must be reduced at least 10 times. In the current work, 2 droplets were obtained as a result of the bubble burst. This is encouraging numerical modeling results; however, the results are not sufficient for quantitative entrainment ratio analysis. The present work has emphasized the need for significantly higher computational power for a thorough analysis. The future work will focus on the simulation of a single bubble, of various sizes, rising and bursting at the free surface. Each bubble size would correspond to a flow regime of a discrete bubble column.
