Category: Transient Plane Source
Abstract: Thermal conductivity of alumina and kaolin clay were investigated as a function of the water content at different stages of drying compared to linear shrinkage. Thermal conductivities of the samples were measured using the transient plane source method with a Hot Disk apparatus. Samples were encapsulated in a polyvinyl film to ensure a constant temperature in the sample while drying. Results found thermal conductivity varied at the beginning as values increased, then decreased significantly at the end of the drying process.
