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 ...
Paper that presents a slightly modified version of the early transient plane source technique which allowed the easier measurement of thermal transport properties of solid materials. A series of building materials were tested spanning thermally conductive to thermally insulating materials including extruded polystyrene, polymethyl methacrylate (PMMA), stainless steel and aluminum. This modified method allow the measurement of thermal conductivity values from 0.02 W/mK to 200 W/mK....
This study looks at U-values and heat transfer for houses built in Libya, of which the majority studied were built in the 1970's when the locally produced building materials didn't consist of any insulating materials. Measurements of thermal conductivity of the various building materials were made. Additionally, the researchers developed a theoretical model that could estimate U-values from measured thermal conductivity values. It was determined that U-values were quite high, ...
Thermal interface resistance results from small gaps and surface geometry mismatches between two materials that make up a composite. Thermal interface resistance is present in most any material that is comprised of two or more components. In the field of thermal interface materials, the majority of novel materials are composites, and thus are subject to thermal interface resistance and thermal boundary resistance (thermal discontinuity at a perfectly bonded interface of ...
Yttria-stabilized zirconia (YSZ) powders containing varying amounts of SiO2 and Al2O3 impurities were plasma sprayed onto metallic substrates and subsequently investigated. The authors were interested in how the impurities affected sintering rates, thermal conductivity, linear contraction, and pore size and architecture among other things. The YSZ coatings were heat treated at 1400°C for 10 hours and then analyzed for the properties mentioned above. A machine was used to measure the ...
