132 二次元流路内の角を曲がる流れにおける液晶高分子溶液の流動構造に関する研究(S34-3 複雑流体の流れとその応用(3),S34 複雑流体の流れとその応用)  [in Japanese] 132 Study on the Flow Induced Structure of Liquid Crystalline Polymer Solution in a Two-Dimensional Channel with a Corner  [in Japanese]

In this study, we have investigated the flow induced structure of liquid crystalline polymer solution in a flow through a two dimensional channel with a corner. The orientation angle and the dichroism were measured with a laser optical measurement system. The orientation angle had smoothly changed from the upstream of the corner to the downstream. A periodic oscillation in orientation angle was observed in the upstream flow, but it became smaller after the flow direction change. The dichroism also became a bit higher in the downstream region. In spite of no significant change in orientation angle and dichroism, a typical texture was obtained at the downstream region in polarized observation.
