Paper that presents a slightly modified version of the early transient plane source technique which allowed the easier measurement of thermal transport properties of solid materials. A series of building materials were tested spanning thermally conductive to thermally insulating materials including extruded polystyrene, polymethyl methacrylate (PMMA), stainless steel and aluminum. This modified method allow the measurement of thermal conductivity values from 0.02 W/mK to 200 W/mK....
The TPS technique was used to measure the thermal conductivity of three different steel samples, which allowed the researchers to analyze the steel critically. Specifically look at was the dependence of thermal conductivity on temperature from room temperature up to 300°C. The obtained results were compared values obtained from other research groups....
Using the TPS method, the authors measured the thermal conductivity and thermal diffusivity of samples of Swedish wood. They also looked at the effect of density, porosity and anisotropy on the measured thermal properties. Both longitudinal and transverse measurements were taken at temperatures ranging from 20°C to 100°C and an increase in temperature resulted in a slight increase in thermal conductivity. The types of mechanisms that lead to heat conduction ...
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. ...
This paper discusses thermal conductivity measurements on homogenous and non-homogenous materials, using three transient methods: Laser Flash Method (LFM), Modified Hot Wire (MHW), and the Transient Plane Source (TPS). This article also compares the non-destructive nature of the MHW, and the TPS methods, to the destructive nature of the LFM. Research conducted on homogenous materials produced comparable results using all three transient methods. However, when testing non-homogenous materials, such as ...
