Thermoconvective Instability in A Porous Maxwell Ferromagnetic Fluid

Abstract

The study considers a porous Maxwell ferromagnetic fluid layer which is assumed to be heated from below.The boundaries are infinite and free-free. AMaxwell model is implicated on this fluid layer under realistic boundary conditions and the Galerkin approach is followed to solve the concerned eigenvalue problemfor which the Rayleigh number is obtained in stationary and oscillatory convection. At stationary state, it is noticed that the Maxwell ferromagnetic fluid behaves similar to a Newtonian ferromagnetic fluid. The effects of concerned parameters are analysed and the results have been depicted both analytically and graphically. It has been noticed that the presence of porous medium delays the convection as compared to the continuous medium. A comparative study between stationary and oscillatory convection results that the oscillatory convection sets in earlier.
