Thermal conductivity of cement composites containing rubber waste particles: Experimental study and modelling

The authors of this article look to use shredded waste tires as a component of a cement composite in order to reuse the discarded material as well as improve the thermal properties of the composite. The TPS method was used in order to determine thermal conductivities of the dry components of the composite, and the auto-coherent homogenisation model was used to determine the thermal conductivity of the rubber/cement/air ...

Specific Heat Measurements with the Thermal Constants Analyser

This work introduces a direct method for measuring the specific heat of solids, using the Transient Plane Source Technique (TPS). To begin, a sample is placed into a thermally conductive holder, surrounded by a thermally insulating material. A thermally conductive sample holder is used, to limit the time it takes to achieve a temperature equilibrium between the holder and the sensor. Insulating the sample holder is to minimize heat loss ...

Thermal Conductivity Enhancement Dependent pH and Chemical Surfactant for Cu-H2O Nanofluids

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 ...

Thermal Conductivity of Nitrogenated Ultrananocrystalline Diamond films on Silicon

Thermal conductivity testing was done on nitrogenated ultrananocrystalline diamond films on silicon. Temperature dependence on thermal conductivity was measured using these two techniques. A decrease in thermal conductivity was observed with the introduction of nitrogen addition. It was observed that MCD had the highest thermal conductivity followed by UNCD at 25% nitrogen and UNCD at 0% nitrogen....
