Abstract:According to the characteristics of gas thermal bubbling in the sea, along with the gas?liquid mass and heat transfer process, the coalescence model of thermal bubbles and wake microbubbles was set up on the basis of bubble population balance equation model. Corresponding coalescence efficiency was solved and validated by relevant experiment. The results showed that 1 mm was the bubbles coalescence critical radius. The coalescence efficiency increases obviously with the increasing of radius below critical radius. When the radius is bigger than the critical radius, it had a reverse rule. The coalescence efficiency increased stepwise as the increasing of big bubbles numerical density. When the big bubbles numerical density was equal with microbubbles, the effect of defoaming efficiency was well.
