This paper examined the properties that affected the thermal conductivity of Aluminum Oxide (Al2O3) nanofluids with a base fluid of propylene glycol. Samples were prepared with volumetric percentages of 0.2%, 2%, and 3% Al2O3, and 22 replicates were completed over time. A Thermtest Transient Plane Source TPS measured the thermal conductivity of the nanofluids. Results showed that the 3% Al2O3/propylene glycol solution had the highest thermal conductivity....
Adding thermally conductive materials and consolidating adsorbents in a thermally conductive porous matrix is one way to improve heat transfer in sorption beds. The aim of this study was to develop a model that predicts the effective thermal conductivity of consolidated composite adsorbent containing graphite flakes. A thermal constants analyzer TPS measured the thermal conductivity of consolidate adsorbent graphite flakes using the transient plane source (TPS) method. The results showed ...
Silver (Ag) has the highest thermal conductivity of all metals, making it an attractive nanoparticle for use in heat transfer systems. The shape of nanoparticles influences their thermal conductivity, so three varieties of Ag nanoparticles were tested in this study. The Thermal Constants Analyser measured the thermal conductivity of Ag nanospheres (NSs), nanowires (NWs), and nanoflakes (NFs) between 10-30 °C using the transient plane source (TPS) method. Results showed that ...
Nanofluid research is focused on two specific areas of testing: synthesizing new nanofluids with enhanced thermal properties, and finding new applications for nanofluids. Nanofluids are conventional heat transfer fluids with suspensions of thermally conductive nanoparticles. In this study, TiO2 (titanium dioxide) nanoparticles are used to enhance the base fluid propylene glycol (PG). The Thermal Constants Analyzer measured the thermal conductivity of the TiO2/PG nanofluid using the transient plane source (...
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. ...
