Gravity Simulation of Natural Convection in Magnetic Fluid

Transition phenomena for the natural convection of a magnetic fluid in a square cavity was studied numerically for an externally imposed magnetic field. In the present study, particular attention was focused to verify heat transfer characteristics for non-gravity situation when the magnetic field was imposed. By applying magnetic fields the convection state many be largely affected improving heat transfer characteristics followed by various flow transitions in the non-gravity simulation. It was revealed that magnetic field could enhance the convection and consequently improves heat transfer characteristics, indicating that the magnetic field would be used as a substitute for the gravity in the zero-gravity situation of space.
