Thermal-magneto-mechanical stability analysis of singlewalled carbon nanotube conveying pulsating viscous fluid
R. Selvamani, M. Mahaveer Sree Jayan and Marin Marin

    In this study, the vibration problem of thermo elastic carbon nanotubes conveying pulsating viscous nano fluid 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 non local theory. The instability domain and pulsation frequency of the CNT is obtained through the Galerkin's method. The numerical evaluation of this study is devised by Haar wavelet method (HWM). Then, the proposed model is validated by analyzing the critical buckling load computed in present study with the literature. Finally, the numerical calculation of system parameters are shown as dispersion graphs and tables over non local parameter, magnetic flux, temperature difference, Knudsen number and viscous parameter.
