Hydromagnetic Instability of visco-elastic Walter’s (modal B´) nanofluid layer heated from below
Deepak kapil,  Sudhir kumar
In this paper, Hydromagnetic instability of visco-elastic Walter’s (modal B´) nanofluid layer heated from below is numerically and analytically described. For this Perturbation method, Normal mode technique and the dispersion relation has been used.. The effects of the various physical parameters of the system, namely Lewis number, modified diffusivity ratio, nano particle Rayleigh number and magnetic field on the stationary convection have been analyzed both analytically and graphically. The Lewis number, modified diffusivity ratio and nano particle Rayleigh number are found to have destabilizing effect, whereas magnetic field has a stabilizing effect for stationary convection.
Keywords- Nanofluid; Walter’s (modal B´) visco-elastic fluid; Normal mode technique; Oscillatory convection; Rayleigh number; Lewis number; modified diffusivity ratio; magnetic field.
