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%....
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 ...
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 ...
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 ...
