The vibration and instability behavior of viscoelastic single-walled carbon nanotubes (SWCNTs) conveying viscous fluid and embedded in a viscoelastic medium is analyzed based on the nonlocal Euler–Bernoulli beam model. The equation of motion is derived by employing Newton’s method. The frequencies are obtained using the Galerkin method. In-vestigating the influences of the viscoelastic property of SWCNTs and fluid viscosity on the frequency and critical flow velocity is the main aim of this paper. Furthermore, two addition-al terms resulting from combination of fluid viscosity and nonlocal parameter are considered in the presented equation of motion in this work, which are neglected in previous equations. Moreover, the effects of fluid flow velocity, nonlocal parameter, aspect ratio, elastic modulus constant and damping factor of the viscoelastic medium on the frequency and critical flow velocity of SWCNTs are elucidated.
