In the present experiments two arrangements of the electrodes fixed on the inner surface of the circular tube are developed. One is that the four pair of the electrodes is fixed to add the voltages in the peripheral direction. The other is that the electrodes are lined up along the inner surface to add the voltages in the axial direction. The pressure drops are measured when the liquid crystal mixture made of some kinds of the nematic liquid crystal flows in the circular tubes for the constant flow rates. When the voltages are applied on the liquid crystal mixture and removed, the pressure responses of the inlet of the circular tube are measured with the pressure transducer. The diameter of the circular tube is 1.0mm. The isotropic-nematic transition is 90.0℃ and smectic-nematic transition is -44.0℃ for the liquid crystal mixture. The open-loop test facility with the liquid crystal is set in a pyrostat to keep the temperature constant.
