Abstract

Inhomogeneous electric field induced aggregation of metal microspheres suspended in an insulating oil is studied by means of computer simulations. In the present model the metal particles are subjected solely to the forces exerted by the inhomogeneous external electric field and by the fluid; the interparticle interaction and stochastic forces are ignored. The metal clusters grown in the simulation are found to be fractals. At low concentration there is quantitative agreement between the simulations and the experiments of Wen and Lu [Phys. Rev. E 55, R2100 (1997)]. The fractal dimension of the aggregates has power law dependence on the concentration, and the time evolution of the growth process also shows qualitative behavior similar to that in the experiments.
