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 ...
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 ...
Many conventional fluids have low thermal conductivities. Adding thermally conductive nanometer-sized particles to these fluids transforms them into thermally conductive nanofluids. In this study, the thermal conductivity of aqueous alumina and multi-walled carbon nanotube (MWCNT) nanofluids was measured using the transient plane source (TPS) method with a thermal constants analyzer TPS. During each trial, 0.015 W of power were administered to each sample for two seconds. Results of the experiment showed ...
Quad Flat Non-Lead (QFN) devices are sensors used in building designs to control electronic equipment. The temperature of the QFN sometimes exceeds its maximum threshold, which this is primarily due to the encapsulating resin. In this study, the thermal conductivity of the resin was tested for the QFN16b, QFN32b, and QFN64b using the Transient Plane Source (TPS). Power levels between 0.1 W and 1.0 W were administered through the ...
