Abstract

The paper introduces a kinetic theory based particle pair model for magnetorheological fluid characterization. Fluid constitutive equations are derived from an analysis of the motion of a pair of particles subject to hydrodynamic and magnetic field forces. The effect of neighboring particles from the same chain on the magnetic force is included. The model can predict fluid behavior when particles separate or remain in contact during flow. For yield stress predictions, the case when particles separate is considered. Predictions for the yield stress are compared with experimental data and with othertheoretical models. Predictions from the proposed model are in good agreement with experimental data.
