This volume covers topics in cavitation bubble dynamics, sound and wave propagation in bubbly mixtures, bubbles in flow, sonoluminescence, acoustic cavitation, underwater explosions, and bursting bubbles at a free surface. The physics and chemistry of sonoluminescence and the modelling of jet impact during bubble collapse are examples of issues which enjoy considerable attention. One of the most exciting areas of contemporary chemistry and physics is single bubble picosecond sonoluminescence. The high pressures and temperatures generated over picoseconds, coupled with previously unachievable rates of reaction have recently attracted attention. High temperatures and pressures are often associated with symmetric bubble collapse; however, asymmetric collapse can typically lead to the development of a damaging ultra-high-speed liquid jet that pierces the collapsing bubble. Occurrence of this high-speed jet was reported at both the microscale in laser surgery and the large scale in underwater explosions, but it is also frequently present in collapsing cavitation bubbles.The volume contains information on the latest research on a range of topics in bubble dynamics, underwater acoustics and multiphase flow and is a reference for scientists and engineers conducting research in these areas.

This volume contains papers presented at the IUTAM Symposium on Bubble Dynamics and Interface Phenomena held at the University of Birmingham from 6-9 September 1993. In many respects it follows on a decade later from the very successful IUTAM Symposium held at CALTECH in June 1981 on the Mechanics and physics of bubbles in liquids which was organised by the late Milton Plesset and Leen van Wijngaarden. The intervening period has seen major development with both experiment and theory. On the experimental side there have been ad­ vances with very high speed photography and data recording that provide detailed information on fluid and interface motion. Major developments in both computer hardware and software have also led to extensive improvement in our understand­ ing of bubble and interface dynamics although development is still limited by the sheer complexity of the laminar and turbulent flow regimes often associated with bubbly flows. The symposium attracts wide and extensive interest from engineers, physical, chemical, biological and medical scientists and applied mathematicians. The sci­ entific committee sought to achieve a balance between theory and experiment over a range of fields in bubble dynamics and interface phenomena. It was our intention to emphasise both the breadth and recent developments in these various fields and to encourage cross-fertilisation of ideas on both experimental techniques and theo­ retical developments. The programme, and the proceedings recorded herein, cover bubble dynamics, sound and wave propagation, bubbles in flow, sonoluminescence, acoustic cavitation, underwater explosions, bursting bubbles and ESWL.
