N2 - In this study, the instability of multi-walled carbon nanotubes (MWCNTs) conveying fluid is studied based on an Euler-Bernoulli beam model. The van der Waals (vdW) interaction between different CNTs was taken into consideration, and the Galerkin discretization approach was used to solve the coupled equations of motion. Numerical simulations show that the interlayer vdW interaction plays a significant role in the natural frequencies and stability of MWCNTs. The critical flow velocities - associated with divergence, restabilization and flutter - were also determined. The effects of the length-to-radius ratio of MWCNTs were examined in detail. Results reveal that the internal moving fluid is important for the instability of MWCNTs that convey fluid. © AES-Advanced Engineering Solutions.
