This paper highlights the use of the transient plane source (TPS) technique to test the thermal properties of porous building materials, such as autoclaved aerated concrete and calcium silicate boards reinforced by cellulose fibers. Transient methods relay multiple thermophysical parameters, such as thermal diffusivity, specific heat, and thermal conductivity, all in one measurement – a highly sought after trait. Measurements were performed to compare the transient method to other methods of ...
Thermal conductivity of heating and cooling fluids with added nanoparticles dubbed 'nanofluids' are used as potential to improve the efficiency of heat transfer fluids using a thermal constants analyser. The Thermal conductivity enhancements of Cu-H2O nanofluids are dependent on the weight fraction of nanoparticles, pH values and sodium dodecylbenzenesulfonate (SDBS) surfactant concentration of nano-suspensions. Combining both the pH and chemical surfactant is recommended to improve the thermal conductivity for ...
This research article proposes the use of a thermal constants analyzer to measure thermal properties of relatively thin samples. Five different metallic samples containing copper, aluminum and brass were used to test the accuracy of the new and improved method. Previously, this method has been used to test the thermal properties of thin metallic sheets, however with the new and improved method, it is possible to measure samples with thicknesses ...
