Investigation of effective thermal conductivities of powders

R. G. Dressler, C. S. Eian
Jun 1952

A simplified analysis was made to determine the effective thermal conductivity of a powder from the fraction of space occupied by the gas and the conductivities of the solid and the gas which make up the powder. In order to check the analysis and to obtain data of current technical interest, tests were conducted to determine the conductivity of magnesium oxide powder in various gases at temperatures between 200 and 800 degrees F.
