Optical Properties at High Temperatures; Dominating Radiative Heat Transfer(<Special Topic>Recent Development in Thermophysical Property Measurements of High-Temperature Melts for Crystal Growth)

Abstract

The mathematical modeling of heat flow requires thermophysical properties relevant to heat transfer mechanisms, i.e. conduction, convection and radiation. Emissivity plays a key role in heat transfer analysis by radiation, which becomes more predominant as temperature rises. This paper focuses on emissivities of metallic melts and reviews recent measurement techniques and data for the emissivity.
