Abstract

Method of the free-convection heat exchange calculation on solid surfaces is presented in 110-1000 К

temperature range. Analytical form for Rayleigh number in a wide temperature range is presented. The results of

the calculation for Rayleigh number are compared with reference data for air. The discrepancy between the

above formula and the reference data does not exceed 10%.

Keywords: free convection, Rayleigh number, heat exchange, properties of gases.
