This paper presents the results of numerical simulations of the interaction of a unit cell of a membrane composed of four open nanotubes and water vapor molecules. A mathematical model was proposed based on the Lenard-Jones potential, and a numerical solution of the equations of motion of a water vapor molecule around a carbon nanotube was constructed. This solution was implemented using the author’s program code in the FORTRAN language. The simulation results show that during the rotation of the unit cell of the membrane, it is possible to change the modes of passage of the membrane in relation to water vapor. These results can be used both in further scientific research and in the creation of various filter materials.

In this work, the process of interaction of a cell of four double-walled nanotubes with a water molecule was numerically simulated. The simulation results show that under normal conditions, water molecules pass through a cell of nanotubes in a plane parallel to the length of the tubes, and in a plane perpendicular to the length, the structure for such molecules is not passable.
