Liquid crystal is one of homogeneous ER (Electro-rheological) fluids in some range of temperature. In the present experiment a liquid crystal mixture is used. The responses of pressure drop are examined when the liquid crystal mixture flows between two parallel-plate electrodes for the constant flow rates. When voltages are applied on the liquid crystal mixture and removed, the pressure responses of the inlet of electrodes are measured with the pressure transducer. At the same time. the liquid crystal mixture between the transparent electrodes made of glass is visualized with the video camera to investigate the time history of the director of the liquid crystal mixture Relation between the flow visualization results and changes of pressure drop is investigated especially for the transient period. In the present experiment, the gap of the electrodes is 0.2mm. The isotropic-nematic transition is 90.0℃ and smectic-nematic transition is -44.0℃. The open-loop test facility with the liquid crystal is set in a pyrostat to keep the temperature constant
