Reflectivity of heatproof materials under radiative-convective heating
Abstract
Data on the surface temperature and spectral emissivity factor under convective and combined radiative-convective heating are presented for various heatproof materials including asbestos, glass ceramics, carbon plastics, and Teflon. It is shown that under combined heating, the surface temperature is determined by the predominant heat flux component. A simple method, which involves illumination of the heated surface with an additional light source, is proposed for measuring the surface temperature and reflectivity of heatproof materials.
