The Barrier Design Guidelines.
NIOSH 1978 Jul:137 pages
Guidelines used for thermal barrier design were evaluated. A literature search was conducted. Radiant exchange predictions utilizing a thermopile, an energy absorption method, an empirical formula, and a computer simulation program, were compared. There were no theoretical thermal barrier design guidelines for hot industrial environments available from the literature. The empirical formula greatly underestimated the radiant exchange calculation when compared with the other prediction methods. The computer program was the most effective tool for predicting radiant exchange for general types of heat sources and absorbers and was within 20 percent of the values for the thermopile or energy absorption methods. Predictions for the contribution of each heat source to total radiant heat load and the placement of the thermal barrier were obtained by the program. The authors suggest that these results will be helpful to the future development of reflective thermal barriers for hot industrial environments.
