To study the dynamic properties of bubbles generated at different air pressures in a liquid-phase flow field, this paper adopted high-speed camera technology and image processing techniques to extract and calculate the features of bubbles. The results showed that in a deionized water field, the bubbles generated at the air pressure of 0.1 MPa had an average diameter of 4.50 mm, and the bubbles generated at the air pressures of 0.2 MPa and 0.3 MPa had average diameters of 5.74 mm and 5.76 mm respectively; notwithstanding the insignificant differences in average data, the probability distribution of bubble diameter had significant differences with different pressures. During the rise of bubbles, their motion trajectory witnessed an increased amplitude of swing with the increase of air pressure; the bubbles generated at different air pressures did not show any significant differences in rising velocities though.
