An unsteady double-diffusive natural convection flow in an inclined rectangular enclosure
subject to an applied magnetic field and heat generation parameter. The enclosure is heated and concentrated from one side and cooled from the adjacent side. The other two sides are adiabatic. The governing equations have been solved numerically using a staggered grid finite-difference method to determine the streamline, isotherm and iso-concentration patterns. We have further obtained the local and average Nusselt numbers and local and average Sherwood numbers for various values of buyancy ratio and angles of the magnetic field  by considering three different inclination angles of the enclosure while keeping the aspect ratio fixed. The results indicate that the flow pattern, temperature and concentration fields are significantly dependent on the thermal radiation and the magnetic field angles. It is found that different angles of the magnetic field suppress the convection flow and its direction influences the flow pattern. This leads to the appearance of inner loop and multiple eddies.
