Title

Size-dependent Vibration and Instability of Magneto-electro-elastic Nano-scale Pipes Containing an Internal Flow with Slip Boundary Condition

Pages

  995-1004

Abstract

 Size-dependent vibrational and Instability behavior of fluid-conveying magneto-electro-elastic (MEE) tubular nano-beam subjected to magneto-electric potential and thermal field has been analyzed in this study. Considering the fluid-conveying nanotube as an Euler-Bernoulli beam, Fluid-structure Interaction (FSI) equations are derived by using non-classical constitutive relations for MEE materials, Maxwell’ s equation, and Hamilton’ s principle. Thereafter, taking the non-uniformity of the Flow Velocity profile and slip boundary conditions into consideration, modified FSI equation is obtained. By utilizing Galerkin weighted-residual solution method, the obtained FSI equation is approximately solved to investigate eigen-frequencies and consequently Instability (critical fluid velocity) of the system. In numerical results, a detailed investigation is conducted to elucidate the influences of nanoflow and nano-structure small scale effect, non-uniformity, temperature change, and external magnetoelectric potential on the vibrational characteristics and stability of the system. This work and the obtained results may be useful to smart control of nano structures and improve their efficiency.
