Motion Characteristics of Microbubble in Water

Article Preview

Abstract:

The motion characteristics of microbubble in the water or solution have important influence to crystallization process. In the paper, the movement equation of single bubble was modeled based on force equilibrium, the mechanics factors influence on the single bubble motion were discussed, and the velocity of microbubble was analysed with the different bubble sizes. The results show that the velocity of microbubble in static water is increasing with time increasing, the influence of virtual mass force and Basset force caused by the acceleration on the velocity of microbubble must be considered in the initial stage of microbubble motion. In the processes of microbubble motion, compared with constant microbubble radius the variation laws of velocity fluctuations mean with microbubble radius changing are uniform.
