Low turbulence natural convection in an air filled square cavity. 1. The thermal and fluid flow fields.

Type of article: Article

Summary

The hot and cold walls of the cavity were isothermal at 50 and 10 °C respectively, giving a Rayleigh number of 1.58 x 1 giga. The temperature and velocity distribution was systematically measured at different locations in the cavity. An experimentally obtained contour plot of the thermal field and a vector plot of the air flow in the cavity are reported for low turbulence natural convection in such cavities for the first time. The wall shear stress and the local and average Nusselt numbers are also presented. The results can form experimental benchmark data and will be useful for CFD code validation.
