Vibration analysis of curved nanotube conveying fluid and nanoparticle considering surface and non-local effects

Abstract

Nanotubes could be fabricated in different shapes for various applications, as they have the possibility of changing curvature. Vibration and stability of a curved nanotube conveying fluid and nanoparticle are investigated considering surface and non-local effects. The surface effects are considered in the nanotube inner and outer layers. The obtained equation is discretized using the Galerkin method. The main parameter effects on the stability and the first two modes are illustrated, including the total opening angle, the nanoparticle mass-ratio, the non-local parameter, the surface-effects parameter, and the nanoparticle position. They show significant effects on the dynamic behavior of the nanostructure.
