Effect of Internal Heating on Radiant Heating of One-Dimensional Semitransparent Media

Abstract

The temperature response and the steady state temperature distribution and heat flux for the radiant heating of a one-dimensional semitransparent medium were analysed with consideration of the emission of radiation from the medium. Under the present experimental conditions, the analytical results agreed fairly well with the experimental results, and so the present theoretical analysis was found to be valid. It was found that the effect of internal heating is greatly concerned in the temperature response and the steady-state temperature distribution and heat flux, and that its extent is dependent upon the values of the monochromatic optical thickness of the medium and the monochromatic emissivity of the boundary wall within the main frequency range of incident radiation.
