1603 液晶マイクロモータ駆動に関する数値シミュレーション(OS16-1 非ニュートン流体の流動現象,オーガナイズドセッション)

Abstract

We have numerically simulated the liquid crystalline micromotor, using the Leslie-Ericksen continuum theory. When an electric field is applied between concentric cylinders, the liquid crystalline flow called the back-flow is induced due to the reorientation of the liquid crystalline molecules. The flow causes the shear stress at inner cylinder surface and the rotation of the inner cylinder occurs. The rotation speed of inner cylinder increases with decrease of the inner cylinder radius.
