Development of an automated probe for thermal conductivity measurements
Abstract
A transient technique was validated for making thermal conductivity measurements. The technique incorporated a small, effectively spherical, heat source and temperature sensing probe. The actual thermal conductivity measurements lasted 30 seconds. After approximately 15 minutes of data reduction, a value for thermal conductivity was obtained. The probe yielded local thermal conductivity measurements. Spherical sample volumes less than 8 cu cm were required for the materials tested. Thermal conductivity (and moisture) distributors can be measured for relatively dry or wetted samples.
