The flow of an electrorheological suspension in cells of different geometries

Using experimental evidence and simple models the modification of the electrorheological effect by three different electrode configurations (spiral ribbons, coaxial cylinders, and planar electrodes at various angles) and by other parameters (water content, mixing time, temperature, operating time and storage time) is described. Cells of variable geometry offer a useful means of regulating the electrorheological effect and that any loss of performance with life is associated with structural changes in the fluid, such as coagulation.
