• Simulation of alignment of CNTs or VGCFs by the water contraction flow was carried out. The flow was reproduced using ANSYS CFX software and then the dynamic motion of CNTs transported by the flow was calculated. 2D contraction flow with upstream and downstream channel flows was used. And a CNT was modeled as a dumbbell-like element. The orientation angle of the elements at the end of the downstream flow channel was estimated. It is found that the ratio of upstream channel width to downstream channel width is the major factor for the alignment of the elements. And the absolute value of average angle 0.29 degree and minimum standard deviation 4.98 degree were obtained with upstream channel width 25 cm, contraction length 20 cm, downstream channel length 10 cm, and downstream channel width 1 cm.
