| Zusammenfassung | This paper deals with the numerical simulation of turbulent natural convection in cavities heated from the side. Three cases are considered: an air-filled square cavity of size 0.75 m, a water-filled cavity of the same size, and a 20 times larger water-filled cavity. The Rayleigh numbers of these applications reach from 1.46·10-9 to 2.77·1015. For the air-filled cavity, the results are validated by comparison with experimental data from Tian & Karayiannis. In addition, the investigations have the practical background to provide support for improving temperature measurements of liquids in large storage tanks. |
