A two-fluid continuum model is developed to describe mass transport in electro- and magnetorheological suspensions. The particle flux is related to the field-induced and hydrodynamic stresses. Solutions of the resulting mass balance show column formation in the absence of flow and stripe formation when a suspension is subjected simultaneously to an applied electric field and shear flow.
