Comparison Of Theoretical And Computational Ferroconvection Induced By Magnetic Field Dependent Viscosity In An Anisotropic Porous Medium

A. Suresh Govindan, B. Vasanthakumari

Full text: PDF


Ferro convection induced by magnetic field dependent viscosity in an anisotropic porous medium using Darcy model is studied with computational methods. Galerkin method is applied. Linear stability analysis is carried out for both stationary and oscillatory modes. The critical magnetic Rayleigh number is computed for various values of the parameters which characterize the flow. It is found that the increase in magneto viscosity stabilizes the system through stationary mode;Numerical computations are made and illustrated graphically.
