133 Effect of Rotating Electric Fields on the Flow of a Liquid Crystal Mixture

Abstract

Flow visualization of a liquid crystal mixture in mini cylinders is conducted under application of the rotating electric fields. The mini cylinder with the electrode strips on some parts of the inner surface of the cylinder is used. The cylinder is 2.0mm in length and 1.1mm in diameter. The three-phase alternating currents are used as the rotating electric fields. The frequency or the amplitude of the voltages is changed to investigate the effect of the unsteady electric fields on the flow phenomenon of the liquid crystal mixture. When the frequency and the voltage of the three-phase voltages are 60Hz and 255V the rotation speed of the liquid crystal is 26.0 r.p.m.
