Type of article: Article

Summary

GOOD THERMAL CONTACT IS MAINTAINED BETWEEN THE HEAT SOURCE AND SINK AND TWO GEOMETRICALLY SIMILAR SPECIMENS. A THIN COPPER HEATER PLATE IS COMPRESSED BETWEEN THE TWO SPECIMENS AND THE TEMPERATURE DIFFERENCE IS MEASURED BETWEEN THE HEAT SOURCE AND THE TEMPERATURE CONTROLLED HEAT SINK. THERMAL CONDUCTIVITY IS DETERMINED AT STEADY STATE CONDITIONS BY THE DIFFERENTIAL METHOD WHILE THE DIFFUSIVITY IS DETERMINED FROM TRANSIENT MEASUREMENTS COMBINED WITH AN ANALYTICAL SOLUTION TO THE ONE DIMENSIONAL SOLUTION OF THE DIFFUSION EQUATION.
