Type of article: Article

Summary

AN INVESTIGATION WAS CONDUCTED TO DETERMINE THE THERMAL CONTACT CONDUCTANCE OF PACKED BEDS OF SPHERICAL PARTICLES IN CONTACT WITH FLAT SURFACES. BEDS COMPRISED OF 4 MATERIALS, ALUMINIUM 2017-T4, YELLOW BRASS, STAINLESS STEEL 304, AND CHRONIUM ALLOY AISI 52100, ALL IN CONTACT WITH FLAT STAINLESS STEEL 304, SURFACES WERE EVALUATED IN A VACUUM ENVIRONMENT, AT A MEAN INTERFACE TEMPERATURE OF 339 K (66 DEG C). AN ANALYTICAL EXPRESSION WAS DEVELOPED WHICH IS AN ACCURATE METHOD OF PREDICTING THE THERMAL CONTACT CONDUCTANCE AT THE INTERFACE BETWEEN BEDS OF SPHERICAL PARTICLES AND NOMINALLY FLAT SURFACES.
