Haar wavelet method for nonlinear vibration of magneto-thermo-elastic carbon nanotube-based mass sensors conveying pulsating viscous fluid

In this study, the vibration problem of thermo-elastic carbon nanotube mass sensors conveying pulsating viscous nanofluid subjected to a longitudinal magnetic field is investigated via Euler–Bernoulli beam model. The controlling partial differential equation of motion is arrived by adopting Eringen’s nonlocal theory. The instability domain and pulsation frequency of the CNT are obtained through Galerkin’s method. The numerical evaluation of this study is devised by the Haar wavelet method. Then, the proposed model is validated by analysing the critical buckling load computed in the present study with the literature. Finally, the numerical calculation of system parameters is shown as dispersion graphs and tables over nonlocal parameter, magnetic flux, temperature difference, Knudsen number, mass ratio and viscous parameter.
