基于OpenFOAM的气泡运动特性三维数值研究

he research of the process of bubble movement in the water and the bubble jet have great application value to shipbuilding and chemical industry. This article simulated the movement of bubble rising in still water, studied the process of bubble shape deformation, the velocity field of fluids around the bubble, the kinematic velocity and acceleration of bubble and the trend of these physical parameters, analyzed the emergence and development of bubble jet under the single bubble situation and probe the difference between single-bubble situation and double-bubble situation and the amalgamation of two bubbles. The result reveals that OpenFOAM can simulate the process of rising bubble in water accurately and be adequate to study the three dimensional kinetic characteristics of bubble.
