In order to address the bubble formation and movement in air-water two-phase flow,single bubble rising in stagnant water is experimentally studied by digital image *** are released individually from the submerged orifices with different diameters(1.81 mm,2.07 mm,2.98 mm,3.92 mm)at different detachment *** are recorded by a high-speed video camera and processed by digital image processing technique. The factors impacting the formed volume of bubble are *** experimental results showed that a threshold of gas flow rate(400 mm 3 ·s- 1)divides the bubble formation into two regimes:the constant volume regime and the growing volume *** for the growing volume regime,the surface tension is taken into *** bubble volume is consisted of two parts:the surface tension impacting part and the gas volume flow rate impacting *** improved correlation for bubble volume prediction is developed for the two regimes and better coincidence with the experiment data than the previous models is obtained.
