摘要

A double shell-potential flow model is developed to study the free vibration of single-walled carbon nanotube (SWCNT) conveying water. Water is divided into the absorbed layer of water molecules and the water flow in the center of the SWCNT. The SWCNT and the internally absorbed layer of water are modelled as two-layer thin shells coupled via the interlayer van der Waals (vdW) interaction. It is shown that the vdW interaction is responsible for an upshift in the frequency of the SWCNT and an improvement of the system stability. Results also reveal that the internal moving water plays an important role in the instability of system whereas it has very little influence on the dynamic characteristics of the SWCNT. It is hoped that the paper can provide a new and efficient approach for the study of the general dynamic behavior of fluid-filled nanodevices.
