N2 - Research on the behavior of bubble collision has always been one of the focuses in the scientific field. This work focuses on the kinematics and deformation of bubbles when impacting the curved boundary with hydrophilicity and hydrophobicity. The impact process of bubbles colliding with the curved wall was recorded by a high-speed camera. The effects of wettability and radius of curvature were analyzed. The results show that when the bubble collides with the hydrophilic curved wall, it will bounce many times until it leaves the wall. Aiming at the phenomenon of liquid film extrusion rupture, a theoretical model is established to deduce the prediction formula of liquid film induction time, which is mainly related to the thickness, the critical rupture thickness, and the compression speed of the liquid film. The prediction error is less than 5.0%.
