抄録

To develop a simulation software which is able to predict the filling processes of a nematic liquid crystal into a liquid crystal cell, we present a basic model for the filling processes and its computational procedure. The Leslie-Ericksen theory is used as a constitutive equation, and the Hele-Shaw approximation is applied in order to simplify the modeling and to reduce computational power. We also employ a reasonable approximation concerning the director, where the director is not affected by the velocity distribution, but is determined uniquely by the director angle anchored on the liquid crystal cell walls. Input data are cell size, position and size of injection holes, anchoring angles of the director, and viscosities of a liquid crystal. The software can predict free surface lines to move upwards smoothly with time, and effects of the input parameters on the filling time are numerically evaluated.
