Conference Paper

Particle-particle interaction forces due to simple shear motion of particles relative to each other are investigated. The particle-particle interaction force originates from the force balance equations derived for a single particle and extended to the group. A closed form is obtained using a combined collision sphere and REV approach. Rewriting in terms of a particle viscosity and rate of strain yields an expression which is similar to that proposed by [1]. © 2010 American Institute of Physics.
