A reappraisal of the computational modelling of carbon nanotubes conveying viscous fluid

By using the Euler–Bernoulli classical beam theory to model the nanotube as a continuum structure, a reevaluation of the computational modelling of carbon nanotubes conveying viscous fluid is undertaken in this paper, with some fresh insights as to if the viscosity of flowing fluid does influence the free vibration of the nanotube. It is found that during the flow of a fluid through a nanotube, modelled as a continuum beam, the effect of viscosity of flowing fluid on the vibration and instability of CNTs can be ignored.
