Summary

AN INVESTIGATION INTO THE HEAT TRANSPORT THROUGH INSULATION POWDER EVACUATED UNDER HIGH VACUUM, IN WHICH AN ALUMINIUM POWDER WAS ADDED AS A RADIATION SHIELD. EXPERIMENTS ON HEAT FLUX IN THE POWDER WERE CARRIED OUT FROM ROOM TEMPERATURE DOWN TO LIQUEFIED HELIUM TEMPERATURE, THUS GIVING THE RELATION BETWEEN THE HEAT FLUX AND TEMPERATURE. THE GENERAL SOLUTION FOR TOTAL HEAT TRANSFER FOR COMBINED RADIATION AND CONDUCTION OF WANG AND TIEN WAS APPLIED AND COMPARED WITH EXPERIMENTAL RESULTS. A QUANTITATIVE DETERMINATION WAS MADE.
