Identification Of Effective Thermal Conductivity Of Molten Glass

A method for high accuracy identification of the effective thermal conductivity of glass has been developed. For clear and tinted glass, it can be obtained by fitting the experimental and simulation temperature profiles. From simulations, it has been found that the experimentally measured thermal conductivity of glass at high temperatures contains an error of approximately 30%. To apply the method, an experimental furnace has been designed so that it has sufficient volume to avoid the effect of radiation from the walls.
