Abstract
In this paper linear stability analysis for the onset of convection in a Darcy Maxwell Buongiorno’s nanofluid layer with horizontal magnetic field has been done. It is assumed that nanoparticle flux is zero on the boundaries. Both stationary and oscillatory convection are investigated using normal mode technique. It is found that critical Rayleigh Number increases with an increase in the magnetic Chandrasekhar number. Stability of system has been investigated with effects of Lewis number, concentration Rayleigh number, modified diffusivity ratio and magnetic field. For stationary as well as oscillatory motion, magnetic field is found to stabilise the nanofluid layer. The effects of various parameters on thermal Rayleigh Number have been presented graphically.
