Abstract

Two-dimensional numerical studies were performed for investigation of the effect of thermophysical properties of solid walls on turbulent convective - radiative heat transfer in an air filled square cavity. The main attention was paid to the influence of thermal conductivity ratio 1 ≤ κ1, 2 ≤ 1000 and an emissivity of internal surfaces of the solid walls 0 ≤ ε <1 on velocity and temperature fields. Numerical results were obtained by means of the finite difference method. The effect of the governing parameters on the average Nusselt number has been defined. The obtained results provide better technical support for development and research of energy-efficient building materials.
