Sonoluminescence from the unstable collapse of a conical bubble
Sonoluminescence from the unstable collapse of a conical bubble
An experimental bubble collapse is designed such that a gas bubble expands slowly into a conical hollow through a reduction in the static pressure. When this pressure is rapidly released, the resulting liquid shock causes the bubble to collapse into the cone. Ideally a radial divergence or convergence of the liquid in the cone will follow the same geometry as that for a spherical pulsating bubble. Pressure transducers within the liquid at the base of the cone and at the cone apex, are able to detect rebound shocks and the pressures at the centre of the bubble, respectively. Sonoluminescence is detected from the collapse

Abstract
An experimental bubble collapse is designed such that a gas bubble expands slowly into a conical hollow through a reduction in the static pressure. When this pressure is rapidly released, the resulting liquid shock causes the bubble to collapse into the cone. Ideally a radial divergence or convergence of the liquid in the cone will follow the same geometry as that for a spherical pulsating bubble. Pressure transducers within the liquid at the base of the cone and at the cone apex, are able to detect rebound shocks and the pressures at the centre of the bubble, respectively. Sonoluminescence is detected from the collapse
