A numerical analysis is performed on the flow characteristics of an electrorheological (ER) fluid when fully developed ER fluid flow in a channel is instantly subjected to electric fields. The Bingham plastic model is used to describe the ER fluid behavior. The flow field is assumed to be incompressible and isotropic. The SIMPLER algorithm with staggered grid system is employed to solve the momentum and continuity equations governing the steady state, laminar flow. The effects of electric field intensity and upper wall velocity changes on velocity profiles are investigated.
