Collapse of a single bubble in a Shvedov–Bingham fluid under pulsating external pressure

Numerical and analytical study of the behavior of a spherical bubble in an ideal fluid, a viscous medium and an incompressible viscoplastic medium with a yield strength under time-varying periodic pressure at a sufficient distance from the surface of the bubble is carried out. Different modes of collapse are examined and classified. The critical values of the key parameters that characterize the behavior of the system (one of them is the dimensionless frequency of external pressure) are found.
