Abstract: This paper examines the dynamics of shock induced collapse of an air bubble in water and discusses the resulting collapse geometry, pressure and temperature. FronTier, a front tracking algorithm, is used to resolve the motion of the air/water interface. A series of plane shock intensities and bubble sizes are compared and the collapse geometry is found to be independent of these variations. The pressure and temperature are found to be greater for a smaller bubble and for a more intense shock. High speed droplet impact with an enclosed bubble is also examined. The impact creates a shock wave that is found to interact with the bubble in a way largely similar to the plane shock case.
Description: This paper was presented at the 2nd Micro and Nano Flows Conference (MNF2009), which was held at Brunel University, West London, UK. The conference was organised by Brunel University and supported by the Institution of Mechanical Engineers, IPEM, the Italian Union of Thermofluid dynamics, the Process Intensification Network, HEXAG - the Heat Exchange Action Group and the Institute of Mathematics and its Applications.
