Adding thermally conductive fillers into flexible moulds has been proven to decrease the solidification time of the polymers. The aim of this study was to determine the thermal conductivity, thermal diffusivity, and specific heat of the flexible moulds polyurethane (PU) and silicone rubber (SR) after the addition of aluminum and graphite. Thermal properties were measured using the transient plane source (TPS) method. Results showed that the thermal conductivities of particulate ...
Transient plane source (TPS) method is one of the fastest and most accurate ways to measure the thermal properties of smooth, flat samples. This paper aimed to compare the thermal conductivity measurements of several varieties of sensors, especially focusing on the accuracy of sensors used for cylindrical samples. The TPS method measured the thermal conductivity of a one-dimensional finite slab. The TPS sensor had the most accurate results compared to ...
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 ...
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 ...
Finding uses for plastic is becoming increasingly important because it has one of the lowest recycling rates among fabricated materials. Wood, on the other hand, is a natural material that is referred to as biomass and is being used as a clean energy source. Researchers are now looking to form a composite pellet of wood and plastic which would simultaneously increase the value of the fuel while providing a practical ...
