Convection in a ferromagnetic fluid occupying a vertical enclosure

Convection in ferromagnetic fluids occupying a rectangular vertical slot is studied with uniform heat flux along the vertical walls. The top and bottom walls of the two -dimensional cavity are impermeable and adiabatic, while the vertical walls are impermeable. A closed form solution based on the Oseen -linearization technique and also similarity analysis is obtained. Magnetisation and buoyancy arising due to differential heat flux at the walls give rise to convection. The effect of various parameters on the boundary layer velocity is clearly brought out. It is found that the effect of the magnetisation is to increase the Nusselt number
