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 ...
A sample of methane hydrate was prepared and analyzed by the TPS method (from 263 K to 278 K) in order to determine the thermal conductivity of the sample. The methane hydrate was prepared from methane gas and sodium dodecyl sulfate (SDS) solution. The thermal conductivity of the impacted sample was compared to that of the unimpacted sample. It was determined that methane hydrate has glasslike thermal properties....
Since cracking in concrete is usually caused by thermal processes, relevant thermophysical properties such as heat capacity and thermal conductivity are important. This article details the measurement of thermal conductivity and heat capacity using the transient plane source method of two different (0.3 and 0.4) water-to-cement (w/c) ratio hydrated cement pastes. These thermophysical properties are measured during the initial application of the cement as well as over a period of 28 days. ...
The 'graphene-like' mechanical exfoliation of Bi2Te3 films is shown to have a significant effect on the thermoelectric properties of these films. The modification of thermal conductivity due to exfoliation leads to enhanced thermoelectric properties, known as figures of merit (ZT).Two different experimental techniques were used in order to determine the thermal conductivity of the exfoliated films: transient plane source (TPS) and laser flash technique (LFT). Annealing was performed ...
Outlines the problems with measuring the thermal conductivity of low-density insulating materials and addresses this by proposing a three layer method for the accurate measurement of thermal conductivity. This method involves a sample being placed between two conducting brass plates (one heated via hot plate) and monitoring the temperatures of these two plates as the experiment progresses. Mathematical equations are derived in order to make an accurate model for thermal ...
