The use of the transient hot wire method has previously displayed that the thermal conductivity of fluids can be significantly increased by introducing nano-particles. The paper discusses the known methods for predicting the thermal conductivity and finding correlations amongst data. When preforming initial simulations employing the Finite Element Method (FEM), this paper shows that there is still substantial experimental progress to be ...
This article investigated the effects of silver addition to copper-aluminum (Cu-Al) alloys. These effects were studied by observing the microstructural, thermal, and mechanical properties of the alloy through a variety of methods. A Thermal Constant Analyzer was used to determine the thermal properties (specifically the thermal conductivities) of the alloys by implementing the transient plane source (TPS) method. From this method, it was found that the thermal conductivity and diffusivity ...
Thermal characteristics of polymer composites are similar to the properties of metal, with the mechanical properties being similar to plastics. Thermal conductivity of a polymer composite depends on geometry of the filler, and interaction and dispersal of the filler within the polymer matrix. In this study, thermal conductivity of copper and Al₂O₃ filled polymer composites were investigated. A Thermal Constant Analyzer was used to measure thermal conductivity of the ...
In this study, sintering parameters in conventional pressure-less sintering are analyzed and the effects of uncoated, Cu(Ni)-coated, and Cr-coated diamond particles are compared for their bulk thermal conductivities. Thermal conductivity was measured at room temperature using a Thermal Constant Analyzer. The addition of diamond particles caused a decrease in the thermal conductivity due to facial air gaps in the composites....
The ability of Cu-H2O nanofluids to perform as phase change materials (PCMs) is investigated. The supercooling behavior of the nanofluids was determined as a function of copper nanoparticle concentration. The contact angle and thermal conductivity of this PCM were also determined experimentally. Based on the experimental results, the authors conclude that these nanofluids could be useful in thermal energy storage applications....
