Abstract
This research discusses flows inside a carbon nano tube(CNT) by molecular dynamics simulation. For the fluid molecules, oxygen molecules and virtual monoatomic molecules whose size and weight are similar to those of O_2 are considered. When the diameter of the CNT is very narrow, the flow rate of the oxygen flow becomes larger than that of the virtual monoatomic molecules, though generally the flow rate of the oxygen molecules is similar to that of the virtual monoatomic molecules. From this result, when the diameter of the CNT is very narrow, it is found that the effects of rotation and difference of the molecular structure cause the different flow characteristics.
