Comprehending bubble movement is crucial in cavitation research. In this study, a numerical analysis method is used to investigate the hydrodynamic behavior of a single void, and the relationship between the velocity, force, impact load, and wall shear rate of the void with time and infinite wall distance is illustrated. The results reveal that the pressure generated by the cavitation collapse is associated with the wall distance. At a later stage of cavitation collapse, the flow field is significantly disturbed, which may induce a secondary flow of fluid near the cavitation and result in an unstable flow. The numerical results are consistent with the theoretical calculation results obtained for the free-field cavitation movement process using the Keller-Miksis model.
