Abstract

The flow of a dense slurry between two parallel walls is modeled in this paper. The flow behavior of the dense slurry is governed by the particle-particle and particle-wall interactions. Fluid film lubrication theory is used to find the unit solutions of interaction between two particles. The unit solutions are applied to a simple case of slurry flow densely packed with neutrally buoyant particles. The dependence of the effective viscosity of the slurry on packing parameters is revealed. The shear viscosity so obtained is intended for use in the analysis of under-fill flows of encapsulant induced by surface tension. An ongoing under-fill flow experiment aimed at validating the shear viscosity model is described.
