EFFECT OF VARIABLE VISCOSITY ON NON-LINEAR FERRO CONVECTION IN ROTATING FERROMAGNETIC LIQUIDS

Non-linear stability analysis of Ferro convection in rotating Ferromagnetic liquids with variable viscosity have been studied numerically using the generalized Lorenz model.The non-linear stability is studied to discuss influence of variable viscosity under gravity condition in a rotating enclosure using the Lorenz model and the results are shown graphically for combined effects of various parameters.We notice that the variable viscosity and heat source suppress the convection.However, due to the presence of variable viscosity, V, there is a change in the onset of Ferro convection.
