- Bubble-structure interactions are fundamental for many engineering applications, such as airgun technology, cavitation effects on structures, ultrasonic cleaning and underwater explosion, in which the structures are movable. The interactions are usually strongly and nonlinearly coupled. However, the existing methods are only suitable for small bubble deformation or fixed structures. This paper presents a 3D fully coupled model for large bubble deformation and collapse, allowing motions of structures, which are supported by two novel numerical techniques. The new model is carefully tested for different cases and validated by experimental results and can be widely applied to the problems listed above
