Abstract

It is well-known that the defect structure of the molecular orientation field arise in a liquid crystalline material when the material is quenched from on isotropic phase to a liquid crystalline phase. The defect structures annihilate when two different types of the defects come together. In this annihilation process of a pair defects, the flow may be induced in the liquid crystalline material. In this study, we have performed the numerical simulation of the liquid crystalline flow induced by a pair of defects. The Doi's theory with Marrucci-Greco potential is used in the simulation, and the orientation probability density function is replaced with a series of spherical harmonic function. From the simulation results, it is found that the four flow velocities induced during the defect annihilation. Furthermore, the fluid velocity become the maximum just after the finish of the annihilation of a paired defects.
