As titanium foams are generally not as widely studied as aluminum foams, the electromagnetic interference (EMI) shielding performance and thermal conductivity of a high porosity reticular titanium foam were determined to further study the performance of titanium foams. From the experimental results, the samples had better electromagnetic shielding performances at low frequencies effectiveness and the thermal conductivity showed a decreasing trend when the porosity of the samples were increased....
In this study, the transient plane source (TPS) technique was used to measure the thermal conductivity and thermal diffusivity of Se85-xTe15Sbx (x = 2, 4, 6, 8, and 10) pellets. These values were then used to determine the specific heat per unit volume of these glasses in the composition range of investigation. It was found that 4 at% of Sb (antimony) results in the critical composition of ...
In this article, the thermal properties and characteristics of a metal hydride alloy in a high hydrogen pressure environment were determined. An instrument was used to determine the thermal conductivity, thermal diffusivity, and specific heat of oxidized and activated Ti1.1CrMn powder under high hydrogen pressures. In doing so, the thermal conductivity of the oxidized powder increased from 0.80 W/m∙K to 1.6 W/m∙K, with increasing hydrogen pressure (from ...
This article aimed to illustrate the Transient plane source (TPS) method’s abilities in measuring the local thermal conductivity of metal foams and detecting their in-homogeneities. A method was used to measure the effective thermal conductivity and thermal properties of powder metallurgical (PM)-aluminum (Al) foams, infiltrated aluminum foams, and PM-Zinc foams. The accuracy of the TPS method was then verified in the determination of defects or density in-homogeneities....
This article looked at the simulation model used to control temperature evolution in the field for Swedish nuclear waste repositories. Heat transport properties of rock are known key factors for the repository layout and were measured using the Transient Plane Source (TPS) method. Compared to all samples tested, results found bedrock dominated by deformed granitoid rocks were characterized by relatively high thermal conductivities. ...
