Insulating materials were made from recycled clay waste using technologies developed by the author were tested for their thermal conductivity using the transient line source technique over a temperature range of 0-60°C. The clay used was mainly composed of kaolinite. A weight reduction was obtained by using wood aggregates. Different weight percentages of wood aggregates (0, 25, 30, 40, 50%) and the thermal conductivity curves are ...
For the prediction of thermal conductivity using theoretical models of a composite or mixture of components, the thermal conductivities of the individual components must be known. In this study, the needle probe method was used to measure the thermal conductivity of a mixture of powder and fluid, and using the law of mixtures (Hashin-Shtrikman bounds) the thermal conductivity of the solid phase is estimated. A much simpler method exists though ...
The authors used the transient plane source technique for measuring the thermal conductivity, diffusivity and specific heat of highly porous materials. This paper helped to demonstrate that the newly developed TPS technique wasn't just for the measurement of isotropic bulk materials. Different samples of wood composites were analyzed. Once measurements were obtained using the TPS method, they were compared to results obtained theoretically using Verma's model for prediction of thermal ...
