On the natural convection of water near its density inversion in an inclined square cavity

Experimental and numerical results of the natural convection of water in an inclined square cavity at temperatures near its maximum density, as published in the literature [J. Fluid Mech. 142 (1984) 363; Int. J. Heat Mass Transfer 30 (1987) 2319], are revisited. These results were thoughtfully reviewed and some inconsistencies were found. The same physical problem is considered in this technical note, using the spectral elements method. Close agreement is obtained with the numerical results of both previous reports and corroborate the observations in [Int. J. Heat Mass Transfer 30 (1987) 2319] about the substantial differences between the numerical results and the experimental data presented in [J. Fluid Mech. 142 (1984) 363] for the temperature profiles.
