Abstract

In this study, the effect of small-scale of both nanostructure and nano-fluid flowing through it on the natural frequency and longitudinal wave propagation are investigated. Here, the stationary and axially moving single-walled carbon nanotube conveying fluid are studied. The boundary conditions for the stationary nanotube is considering clamped-clamped and pined-pined and for the axially moving SWCNT is simply supported end where the left-end has been restrained. To apply the nano-scale for fluid the Knudsen number and to apply the structure the nano-rod model and nonlocal theory are utilized. Next, using the approximate Galerkin method the governing equation of motion is discretized and solved. In addition, the ratio of the natural frequency and phase velocity to the wave number and also the influence of velocities of flowing fluid and axially moving structure on the natural frequency would be studied. It can be shown that the natural frequency and wave propagation velocity are depending to the nano-scale of the structure and fluid flowing through it. So that, by increasing the nonlocal parameter, the natural frequency is decreased and by increasing the Knudsen number the system frequency is increased hence, leading to a bigger wave.
