Abstract

Time dependent solutions to the equations of motion for flow in an electro-rheological valve are developed and discussed in relation to the limiting speed of operation. The fluid is considered to be a homogeneous continuum obeying the Bingham plastic constitutive equation incorporating a yield stress and viscous component. The results show that the speed of response is determined principally by the plastic viscosity and electrode gap irrespective of the yield stress and corroborates earlier work.
