Analysis of thermal conductivity probes for high temperature applications
Description
Various analyses performed to confirm the viability and potential accuracy of a thermal conductivity probe apparatus are summarized and conclusions are presented. The apparatus under consideration was designed for measurements of conductivity of UO2 powders in inert atmospheres at elevated temperatures to 2300 K in support of the Post Accident Heat Removal (PAHR) program at Sandia. Both analytical solutions and numerical computer models are used for study of the apparatus design. The effects of probe thermal mass and limited sample size on measurement accuracy are analyzed and discussed. Results indicate that the designs considered have the potential for accuracies within 5 percent in the conductivity range of interest
