A numerical model is developed to elucidate the effect of sphere structure, including the volume-average permeability and the primary particle size, on flow and drag force of the sphere. The radially varying sphere would have stronger internal electroosmotic flow relative to its homogeneous counterpart and increased primary particles size would enhance intra-sphere electroosmotic flow. ? 2012 Elsevier B.V. |
