Abstract
Homogeneous ER fluid is an ER fluid which consists of a homogeneous fluid o nly; it is neither a suspension nor a blend of immiscible liquids. Various liquid crystals are typical examples of homogeneous ER fluids. Recently, we have found that urethane-modified polypropylene glycol (UPPG) is one of th e very few examples of homogeneous ER fluids which show no liquid crystalli ne order. In order to clarify the mechanism of the ER effect in this fluid, we have studied, in this paper, electrohydrodynamic flow under shear and e lectric field.
