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 ...
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 ...
Many studies have been conducted on nanofluids with bases of water and ethylene glycol. Cyclic alkane, more commonly known as cyclohexane, can be used as the base liquid for cold storage, however minimal research has been conducted with these solutions. This study explores the temperature-dependent thermal conductivity of cyclohexane with copper oxide nanoparticles. Thermal conductivity was measured using the Thermal Constants Analyser. Samples were tested between 10 °C and 50 °C, increasing ...
Smouldering combustion is a slow, low-temperature form of combustion that is used to improve soil health. Extensive research has yet to be completed about smouldering liquid hydrocarbons in a stationary porous medium such as coal tar in sand. This study examined heat transfer in sand under simulated smouldering combustion conditions. The Thermal Constants Analyser was used to measure the thermal conductivity, thermal diffusivity and specific heat of sand at heightened ...
