The numerical analysis of the annihilation process of a paired nematic liquid crystalline defects has been performed using the Doi theory with the Marrucci-Greco nematic potential. The defects with the defect strength +1/2 or -1/2 have an orientation, since they do not show the rotational symmetry of the molecular orientation configuration. When the orientation of one of the paired defects is rotated at the initial state, the defect shows both translational and rotational motions during the annihilation process and the path of the defects is complex in comparison with the case that the defect is not rotated. It is found that the liquid crystalline flow is induced not only by the translational motion of the defects, but also by the rotational motion of the defects.
