Abstract
An analysis is presented of the qualitative response of particles to electric fields, including both drift and diffusion of charges. On this basis, the influence of particle size and particle conductivity on the overall dipole moment, and therefore the interparticle forces, is discussed. Experimental results in a two-dimensional bed show the predicted response to changes in particle size, while variations in optimal frequency response can be explained on the basis of particle conductivity. A maximum reduction in bubble diameter of 25% is achieved with small particles (77μm), while for large particles (700μm) the bubble diameter can be reduced by as much as 85%.
