Abstract
Investigations pertaining to the effect of water density inversion on steady natural convection in an inclined rectangular cavity whose two opposing walls are kept at different temperatures have been carried out experimentally and analytically. Surface temperature of the cold wall is maintained at 0°C, while that of the hot wall is varied from 2°C to 20°C. Photographs and analytical descriptions of the flow patterns, temperature distributions and average Nusselt number are presented. From the present results, it can be understood that the density inversion of water has an important effect on the convection in the fluid layer, and the average Nusselt number is a peculiar function of surface temperature of the hot wall and' inclination angle, unlike previous results about common fluid without density inversion.
