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 paper analyzes the effects of temperature and air humidity on the thermophysical properties of laterite rocks. Thermal conductivity was measured using a thermal analyzer instrument and the sample and sensor were placed in an airtight humidity chamber. In this method, the TPS element acted as both a temperature sensor and heating element. Thermal conductivity was found to increase by 14.7% with an increase in relative humidity of ambient air....
A comparative study was conducted on the properties of lightweight cementitious composites (LWCCs) mixed with four types of filler particles; EPS beads, dry-expanded plastic microspheres, hollow glass microspheres, and fly ash cenospheres. Thermal conductivity was tested using the transient plane source method. Results showed that thermal conductivity of LWCCs are dictated by the volume of lightweight functional filler (LWF) used and are insensitive to the type of LWF....
This article summarizes thermal properties testing on granular salt that has been consolidated under a wide range of temperature, stress, and moisture conditions. Thermal property measurements were taken on four different sample groups: laboratory-consolidated granular salt using domal and bedded salt types, granular salt that was consolidated in situ, polycrystalline salt cores, and a single crystal of halite. Thermal conductivity was measured with transient plane source method. Results show thermal ...
