INVESTIGATION OF RADIATION AND CONDUCTION HEAT TRANSFER IN FIBROUS HIGH TEMPERATURE INSULATIONS

Abstract

The experimental investigation was concerned with understanding the mechanisms by which fibrous insulations attenuate the transfer of thermal energy. Three fibrous insulation materials, Dynaquartz, Sapphire Wool, and Dynaflex, were evaluated for their usefulness in the high temperature environment. Effective thermal conductivities were measured in air, argon, and vacuum up to 2500 deg F. Transmission experiments were carried out to evaluate the relative contribution of radiation attenuation parameters for Dynaquartz.
