Abstract

A modified Stokesian dynamics technique is used in an oscillatory shear field to obtain the elastic and storage modulus of the suspension of spherical particles in a Newtonian liquid. Electrostatic or steric repulsive forces between suspended particles result in a viscoelastic behavior of a concentrated suspension. The mechanism for energy storage is a particle microstructure phenomenon: the compression of the electrostatic potential by hydrodynamic forces stores energy.
