Project overview
An investigation into the excitation of bubble oscillation in bubble clouds generated through electrolysis or gas sparging will be performed. An electrochemical cell with the ability to generate and monitor the effects of a cloud of gas bubble on mass transfer to micro and macroelectrodes will be constructed. The influence individually and as a collective of these gas bubbles will be investigated while under acoustic excitation. Faraday wave motion of the gas liquid interface of the bubble will be detected using a variety of electrodes placed within the solution and in a simulated macro cathode. The modelling of the sound field will enable efficient excitation of the bubbles within the cell. Sound of the appropriate frequency and pressure amplitude will be employed to excite bubble oscillation rather than cavitation of the media. The effect of surface-active components on both the bubble oscillation in this environment and the metal deposits generated electrochemically will be assessed.
