Abstract

Combined non-gray conductive and radiative heat transfer in single glass window using the radiation element method by ray emission model REM2, has been investigated in one dimensional case. The optical constants of the glass window have been determined by using Fourier transform infrared spectrophotometer. The absorption and emission within the glass layer are taken into consideration. The boundary surfaces of the glass are specular. Spectral dependence of radiation properties of the glass is taken into account. Both collimated and diffuse solar and thermal irradiations are applied at boundary surfaces, using the spectral solar model proposed by Bird and Riordan. The simulation has been performed for one position of the Sun at noon true solar time on the 5th of July for three locations in Japan, Sendai, Tokyo, and Sapporo cities. Steady-state temperature and heat flux distributions within the glass layer for each position of the Sun of the three locations are obtained. The radiative heat flux through the glass mediums is the predominant mode compared with the conductive one. Therefore, the temperature distributions within the glass layer are not linear in shape.
