“…The Prandtl number P r is taken to be 0.01 (Vaidyanathan et al, 2005) and the magnetic numbers M 4 , M 5 and M 6 are assumed to be 0.1 . The ratio of mass transport to heat transport  is assumed from 0.03 to 0.011 (Sekar et al, 2006). Figure 1 presents the plots of the critical magnetic thermal Rayleigh number N C versus the nonbuoyancy magnetization parameter M 3 for different values of the temperature dependent viscosity V, S T = -0.002, R S = -500 and k = 0.1.…”

Soret driven ferrothermoconvective instability in multi-component fluids has a wide range of applications in heat and mass transfer. This paper deals with the theoretical investigation of the effect of temperature dependent viscosity on a Soret driven ferrothermohaline convection heated from below and salted from above subjected to a transverse uniform magnetic field in the presence of a porous medium. The Brinkman model is used in the study. It is found that the stationary mode of instability is preferred. For a horizontal fluid layer contained between two free boundaries an exact solution is examined using the normal mode technique for a linear stability analysis. The effect of salinity has been included in magnetization and density of the fluid. The critical thermal magnetic Rayleigh number for the onset of instability is obtained numerically for sufficiently large values of the buoyancy magnetization parameter M 1 using the method of numerical Galerkin technique. It is found that magnetization and permeability of the porous medium destabilize the system. The effect of temperature dependent viscosity stabilizes the system on the onset of convection.

The Soret-driven ferro thermoconvective instability of multi-component fluid in a porous medium heated from below and salted from above in the presence of dust particles subjected to a transverse uniform magnetic field has been analyzed using Darcy model for various values of permeability of the porous medium. The salinity effect has been contained in magnetization and density of the ferrofluid. A small thermal perturbation imparted on the basic state and a linear stability analysis is used for this model for which normal mode technique is applied. An exact solution is obtained for the case of two free boundaries and both stationary and oscillatory instabilities have been investigated. It is found that the system destabilizes only through stationary mode. The non-buoyancy magnetization parameter, the dust particle parameter and the permeability of the porous medium are found to destabilize the system. The results are depicted graphically.

“…Vaidyanathan et al [18][19] investigated the presence and absence of a porous medium on ferrothermohaline. Furthermore, Vaidyanathan et al [20] attempted to study the Soret effect due to ferrothermohaline convection of a sparse distribution and the condition of a porous medium of ferroconvective instability of multicomponent fluid heated from below and salted from above was analyzed by Sekar et al [21][22] for isotropic and anisotropic models. The effect of rotation on thermohaline convection in a ferromagnetic fluid saturating an anisotropic porous medium with Soret effect was obtained by Sekar et al [23] and further investigation was carried out for magnetic field dependent viscosity by Sekar and Raju [24].…”

In the present paper, the effect of temperature dependent viscosity on a Soret driven ferrothermohaline convection heated from below and salted from above subjected to a transverse uniform magnetic field in the presence of an anisotropic porous medium using Brinkman model is studied. For the case of two free boundaries, an exact solution is obtained using a linear stability analysis and normal mode technique is applied. The effect of salinity has been included in magnetization and density of the fluid. The critical thermal magnetic Rayleigh number Nsc for the onset of instability is calculated numerically for sufficiently large values of the buoyancy magnetization parameter M1 using the method of computational Galerkin technique. It is found that non-buoyancy magnetization parameter, permeability of the porous medium, anisotropy effect and temperature dependent viscosity stabilizes the system.
