Professor John Blake spent a considerable part of his scientific career on studying bubble dynamics and acoustic cavitation. As Blake was a mathematician, we will be focusing on the theoretical and numerical studies (and much less on experimental res

A non-equilibrium oscillating bubble within a narrow gap in between two flat perspex plates has, in earlier studies, been reported to show complex behavior when it is centered between the plates. We study here what happens when the bubble is created

The interaction between a spark-generated bubble and an elastic sphere is investigated. A spark-generated bubble is created at various distances horizontally away from a suspended elastic sphere made of silicone rubber or super absorbent polymer (of

Following previous work on the dynamics of an oscillating bubble near a bio-material (Ohl et al 2009 Phys. Med. Biol. 54 6313-36) and the interaction of a bubble with a shockwave (Klaseboer et al 2007 J. Fluid Mech. 593 33-56), the present work conce

In this study, the effect of high-intensity focused ultrasound (HIFU) on Enterococcus faecalis on both planktonic suspensions and biofilms was investigated. E. faecalis persist in secondary dental infections as biofilms. Glass-bottom Petri dishes wit

Oscillating bubbles or non-equilibrium bubbles are known to induce the development of liquid jets in the presence of a nearby rigid boundary. The liquid jets can be useful in many applications such as surface cleaning and drug delivery into biologica

In this paper we experimentally investigate the effect of liquid viscosity on the behavior of a spark generated bubble which is placed closely on top of a thin elastic boundary (membrane). We describe with details the final stages of the bubble-membr

Oscillating bubbles appear in the bodily fluid during many medical treatments, for example in Extracorporeal Shockwave Lithotripsy. We report a systematic study on the complex interaction between two such bubbles and an elastic membrane, which could

The interaction between two different sized (spark created, non-equilibrium) bubbles is studied by using high speed photography. The bubble size ranges from 2 to 7 mm. The experimental results are compared to that of the similar sized bubbles reporte
