概要

• 論文の詳細を見る

• This paper deals with a theoretical investigation of the effects of heat and mass transfer on the impulsive pressure due to the collapse of a bubble in a compressible liquid. It is found that the dynamical behaviour of the bubble strongly depends on heat and mass transfer through the wall of the bubble. The smaller is the initial radius of the bubble, the more violently contracts the bubble, while the higher becomes an impulsive pressure, on the other hand, the shorter becomes the time duration of it. The higher is the temperature of the surrounding liquid, the more slowly contracts the bubble, and consequently it merely radiates a weak pressure wave.
