摘要：
The effect of backflow in defect dynamics is assessed by computing the viscous force on point and line defects that move due to reorientation. It is found that defects with a positive winding number are accelerated while defects with a negative winding number are slowed down by the backflow. The results are in agreement with experimental and numerical results for defect annihilation.
