This study is concerned with the interaction between a violently oscillating bubble and a
movable sphere with comparable size near a rigid wall, which is an essential physical
phenomenon in many applications such as cavitation, underwater explosion, ultrasonic
cleaning, and biomedical treatment. Experiments are performed in a cubic water tank, and
the underwater electric discharge technique (580 V DC) is employed to generate a bubble
that is initiated between a rigid wall and a sphere in an axisymmetric configuration. The …
