Simultaneous measurements of thermal conductivity and diffusivity of Se(85-x)Te(15)Sb(x) (x = 2, 4, 6 and 10) chalcogenide glasses at room temperature

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 ...

Experimental methods for the characterization of thermophysical properties of nanofluids

In 1967, Gustafsson proposed the idea of the transient plane source (TPS) method, but it was not developed until the 1990’s with the help of Gustavsson. The TPS method uses an engraved spiral nickel sensor to simultaneously administer a heat conducting current while measuring the temperature increase of the sample over the time. Transient plane source methods are popular because there is no limit to the sample size, the thermal range ...

The development of a microfabricated transient planar source (TPS) sensor for measuring thermal conductivity of nanofluids

The addition of thermally conductive nanoparticles to conventional heat transfer fluids enhances their performance so they can be used for high-powered applications. However, as nanoparticles are added, the liquid becomes more viscous, which decreases thermal conductivity. Changing the pH of the solution can control the clustering of nanoparticles to maintain and even enhance thermal conductivity. This study used the transient plane source (TPS) method to measure the thermal conductivity of ...

Concentric circular strips model of the transient plane source-sensor 

The mathematical model for a transient plane source (TPS) is based on a number of concentric ring sources with an infinitely small gap between sample and sensor (strips model). The purpose of this article is to create a model that accounts for the size of the sensor, three models were tested the disk, circles, and rings. The circles model gave almost exactly the same values for thermal conductivity as the ...

A numerical study on the theoretical accuracy of film thermal conductivity using transient plane source method 

Currently, there is no research into the accuracy of the transient plane source (TPS) method for measuring the thermal conductivity of thin films. The purpose of this study is to use numerical simulation to determine the accuracy of thermal conductivity measurements of thin films, with the TPS method. The values produced from the TPS method closely resembled those of the numerical simulation. The deviations from the numerical model were caused ...
