The behavior of mutually coupled cavitation bubbles can change considerably when a finite speed of sound propagation in the liquid is taken into account. This holds for the radial oscillations of the bubbles as well as for the interaction (Bjerknes) forces between them. Starting from linear analysis of the equations of motion, nonlinear bubble dynamics is investigated numerically. Some results are reported for illustration of effects that may have significant impact on the modeling of cavitation structures in certain parameter regimes.

    The behaviour of a laser-produced cavitation bubble near an elastic boundary as well as the deformation of the boundary induced by bubble motion are investigated by means of high-speed photography and acoustic measurements. The elastic boundary, used as a tissue phantom, consists of a...

    Using the example of periodically driven multi-bubble systems we demonstrate that it may be misleading to conclude from a successful low dimensional delay reconstruction that the underlying dynamical process is indeed governed by a low-dimensional attractor.

    We derive the equations of motion for N spherical and massless bubbles in an incompressible and irrotational liquid. The bubbles' motion is assumed to be at high Reynolds, low Weber number and collisionless. External acoustic driving and viscous dissipation are included. In particular, we focus...

    This paper presents the results of investigations of the cavitation erosion of metals caused by pressure oscillations excited by means of a hydrodynamic oscillator in cylindrical tubes closed on one end in the absence of fluid flow in them. Intense cavitation zones were created in the region of...

    We consider parametrically stimulated viscous damping of bubble oscillations in a liquid. Monopole bubble oscillations in relatively strong acoustic fields can generate parametrically bubble shape oscillations — higher modes. The higher modes attenuate effectively due to liquid viscosity....

    The generating mechanism of the relaxation oscillation in Multi-Bubble SonoLuminescence (MBSL) is experimentally investigated. The range of liquid temperature and sound pressure amplitude within which the phenomenon occurs are examined. It is found that one of the main causes for changeover from...
