This paper focused on determining the thermal conductivity of multiwalled carbon nanotubes (MWCNTs) and carbon nanofibers (CNFs) that were dispersed throughout n-octadecane as phase change materials (PCMs). The Thermal Constants Analyzer TPS measured the thermal conductivity of the n-octadecane samples at solid and liquid phases using the transient plane source (TPS) method. Results showed that the thermal conductivity of the solid phase n¬-octadecane/MWCNTs samples increased with nanotube concentration. ...
With the increasing popularity of nanofluids (NFs), understanding their thermal properties is critical. In this paper, a thermal constant analyzer measured the thermal conductivity of copper/palladium bimetallic nanostructure-based nanofluids using the transient plane source (TPS) method. Results showed that the addition of the nanoparticles enhanced the thermal conductivity of the nanofluids by approximately 19%....
It is important to understand the thermophysical properties of concrete when it is quickly heated, such as at the Cape Canaveral Air Force Station. In this experiment, the transient plane source (TPS) method measured the thermal conductivity, thermal diffusivity, and specific heat of four concrete samples taken from the Launch Complex 17 at Cape Canaveral. The samples were measured from room temperature up to 300 °C over intervals of 50 °C. Results showed ...
Phase change materials (PCMs) are becoming increasingly important in the field of thermal energy storage. Ionic liquids (ILs) are a group of novelty salts that are liquid below temperatures of 100 °C. To learn more about ILs based on ZnCl2/ChCl and their uses as PCMs, a Thermal Constants Analyzer measured the thermal conductivities of ionic liquids at 25 °C using the transient plane source (TPS) technique. Results indicated that thermal conductivity ...
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 ...
