Abstract
The purpose of the current study is to investigate the effect of temperature dependent thermophysical properties on thermal radiative loading characteristics of an enclosure. The results are studied the effect of heating number (ζ=0.05–500), aspect ratio (A=0.1–1), the number of heaters (N=1–19), on the maximum and mean temperature of system, Nusselt number, and the maximum stream function rate have been quantitatively analyzed. The results reveal that the average heat transfer rate considering temperature-dependent viscosity are higher than considering temperature-dependent thermal conductivity and both temperature-dependent viscosity and thermal conductivity and the stream function are lower.
