The coupling vibration of fluid-filled carbon nanotubes

Carbon nanotubes (CNTs) have substantial promise as nanocontainers filled with fluid in their hollow cavity in nanotechnology. This paper reports the result of an investigation into the influence of internal fluid on the coupling vibration of fluid-filled CNTs. The coupling vibrational behaviour of fluid-filled CNTs under different supported ends, aspect ratio, surrounding elastic medium, mass density of the fluid and layer number is investigated. The results obtained describe the effect of end condition, aspect ratio, surrounding elastic medium, mass density of the fluid and layer number on the coupling natural frequencies. The new features of the coupling vibration of fluid-filled CNTs and some meaningful and interesting results in this paper are helpful for the application and design of nanostructures conveying fluid in which CNTs act as basic elements.
