In this study, the thermal properties of stainless steel, ceramic, and silica aerogels were numerically calculated and then compared to actual test results. A thermal constants analyser measured the thermal conductivities and thermal diffusivities of the samples using the transient plane source (TPS) method. Results showed that the values generated by the numerical simulation were within ±3% of the TPS method values, which verifies the reliability and accuracy of the numerical ...
In an effort to lessen the Urban Heat Island effect, aggregate in road wearing course was replaced in varying amounts with sintered clay or recycled ceramic. The physical and thermal properties of these new mixtures were then examined to determine if they showed improvements over traditional wearing course. It was found that the replacement of aggregate with sintered clay decreased the thermal conductivity and thermal diffusivity. A similar result was ...
Using the transient plane source (TPS) technique, researchers measured the thermal conductivity, thermal diffusivity and specific heat capacity of an electrically insulating ceramic material prepared from kaolin and feldspar. The electroceramic was tested at multiple temperature points to see how it affected thermal conductivity. Thermal properties were strongly affected by temperature, and the ceramic material studied had the highest thermal conductivity and thermal diffusivity at the highest temperature tested. The ...
Very porous ceramics were prepared by the direct foaming method containing 79% kaolinite , based on commercial clay. Ceramics were prepared with different pore volume fractions, and the different ceramics were analyzed using the transient plane source (TPS) technique to measure thermal conductivity. Increasing pore volume fraction led to decreased thermal conductivity....
The transient plane source (TPS) technique was used to measure the thermal conductivity of three ceramic fibres with varying amounts of aluminium content. Specifically, the effect of temperature, press load per unit area and the aluminium content on thermal conductivity was studied. The three ceramic fibres studied were VK-60, ABK and Nextel/VK-80. It was experimentally determined that an increase in aluminium content resulted in decreased thermal conductivity of the ...
