A novel model for vibrations of nanotubes conveying nanoflow

摘要: Abstract In this paper, we have presented an innovative model for coupled vibrations of nanotubes conveying fluid by considering the small-size effects on flow field. By model, demonstrated that ignoring field in a nano-scale fluid–structure interaction (FSI) problem may generate erroneous results. The nanotube has been modeled Euler–Bernoulli plug-flow beam kinematic theory, and formulated bulk viscosity slip boundary conditions nanoflow through Knudsen number ( Kn ), as discriminant parameter. divergence instability phenomenon observed, incorporating various regimes liquids gases. We observed including effect viscosity, is not so influential vibration fluid, compared with results inviscid fluid; however, slip-boundary hypothesis changes drastically, to continuum models.
