Flow structure of water molecules in carbon nanotubes (CNTs) is studied using molecular dynamics method. High density water inside CNTs with diameters of 0.81 to 2.71 nm at a streaming velocity of 100 m/s and a temperature of 300 K is considered with new flow induction models. The results show that the water flow through the CNTs has flat profile that is different from parabolic nature of Poiseuille flow. Hydrogen bond lifetimes are calculated to measure the stability of collective water molecular structure. Comparison with corresponding equilibrium states shows that the stability is not declined by the flow dynamics. Therefore, it can be concluded that the water flow through such small CNTs is pluglike rather than Poiseuille type.
