Air bubbles are a common occurrence in both natural and industrial settings and are a significant topic in the fields of physics, chemistry, engineering, and medicine. The physical phenomena of the contact between bubbles and submerged solid surfaces, as well as the locomotion behavior of bubbles, are worth exploring. Bubbles are generated in an unbounded liquid environment and rise due to unbalanced external forces. Bubbles of different diameters follow different ascending paths, after which they approach, touch, collide, bounce, and finally adsorb to the solid surface, forming a stable three-phase contact line (TPCL). The bubbles are in an unstable state due to the unbalanced external forces on the solid surface and the effects generated by the two-phase contact surface, resulting in different locomotion behaviors on the solid surface. Studying the formation, transport, aggregation, and rupture behaviors of bubbles on solid surfaces can enable the controllable operation of bubbles. This, in turn, can effectively reduce the loss of mechanical apparatus in agro-industrial production activities and improve corresponding production efficiency. Recent research has shown that the degree of bubble wetting on a solid surface is a crucial factor in the locomotion behavior of bubbles on that surface. This has led to significant progress in the study of bubble wetting, which has in turn greatly advanced our understanding of bubble behavior. Based on this, exploring the manipulation process of the directional motion of bubbles is a promising research direction. The locomotion behavior of bubbles on solid surfaces can be controlled by changing external conditions, leading to the integration of bubble behavior in various scientific and technological fields. Studying the dynamics of bubbles in liquids with infinite boundaries is worthwhile. Additionally, the manipulation process and mode of these bubbles is a popular research direction.
气泡在自然和工业环境中都很常见，是物理学、化学、工程学和医学领域的一个重要课题。气泡与浸没在液体中的固体表面之间的接触物理现象以及气泡的运动行为值得探索。气泡在无界液体环境中产生，并由于外力不平衡而上升。不同直径的气泡遵循不同的上升路径，之后它们相互靠近、接触、碰撞、反弹，最终吸附到固体表面，形成稳定的三相接触线（TPCL）。由于固体表面上的外力不平衡以及两相接触面产生的影响，气泡处于不稳定状态，导致其在固体表面有不同的运动行为。研究气泡在固体表面的形成、传输、聚集和破裂行为能够实现对气泡的可控操作。这反过来可以有效减少农业工业生产活动中机械设备的损耗，并提高相应的生产效率。最近的研究表明，气泡在固体表面的润湿程度是气泡在该表面运动行为的关键因素。这使得气泡润湿研究取得了重大进展，进而极大地推进了我们对气泡行为的理解。基于此，探索气泡定向运动的操控过程是一个有前景的研究方向。通过改变外部条件可以控制气泡在固体表面的运动行为，从而实现气泡行为在各个科技领域的整合。研究无限边界液体中气泡的动力学是有价值的。此外，这些气泡的操控过程和方式是一个热门的研究方向。
