We regard carbon nantube junctions as molecular nozzles. Using the reflecting particle method to induce the flow, we analysed the diameter dependence of water flow through nanotube junctions by molecular dynamics method. As the diameter of the downstream nanotube is smaller, the maximum water density at the entrance of the junction region becomes higher and that in the downstream becomes lower, and the acceleration of the streaming velocity becomes larger. As for the temperature distribution, nanoscale cooling effect is observed in the (12,12) nanotube of the (12,12)-(8,8), and (12,12)-(6,6) nanotube junction, while it does not occur in the (12,12)-(10,10) nanotube junction.
