The double diffusive convection of cold water in the vicinity of its density maximum m a rectangular partitioned enclosure of aspect ratio 5 with isothermal side walls and insulated top and bottom is studied numerically, A thin partition IS attached to the hot wall. The species diffusivity of the fluid is assumed to vary linearly with concentration. The equations are solved by finite difference scheme, The effects of position and height of the partition, variable species diflusivity and enclosure width arc analyzed for various hot wall temperatures, It has been found that adding partition on the hot wall reduces the heat transfer. The density inversion of the water has a great influence on the natural convection. When increasing species diffusivity parameter heat, and mass transfer rate is decreased.
