EP/D05849X/1 Acoustoelectrochemistry Imaging System

Project overview

Cavitation events are short-lived gas bubbles that occur under the correct physical conditions. In order to study these events high- speed cameras can be used to understand the dynamics of the interfaces involved and the effects they have of other sensors placed close to them. In this project two camera systems will be developed with the ability to acquire images at high rates (up to 400,000 frames per second). Under these conditions the cavitation events can be viewed in real time and their effects correlated with the data obtained from a number of different sensors placed within the local environment. These sensors will use, for example, electrochemical and acoustic technology to detect how the liquid around the bubble moves and the damage that the bubbles can do to a solid surface. This study will enable the true effects of cavitation, and related bubble phenomena, to be clarified. In addition these camera systems will be used to study the fast motion of aquatic organisms (for example the mantis shrimp) which are suspected to generate large cavitation bubbles as they attack their prey/defend themselves from other predators. Finally the cameras will be used to study the processes that occur at the gas/liquid interface of a breaking wave.
