Session AC - Drops and Bubbles I.
ORAL session, Sunday morning, November 24
Governor's Lecture Hall, Wyndham Anatole Hotel
When bubbles collapse near other bubbles or near a wall, the collapse is often non-spherical. In the case of violent collapses, the heat of compression of the bubble contents is diminished, relative to the case of a spherical collapse. This leads to lower peak temperatures for non-spherical collapsing bubbles, with reduced production of light and of radical species. These issues are explored with a simulation based on the boundary integral technique to handle the fluid mechanics, and integral equation techniques to handle heat and mass transfer within the bubble and between the bubble and the liquid outside.
