This article examined how a variety of mechanisms (layering, Brownian motion, clustering, ballistic phonon motion, thermal boundary resistance, and mass difference scattering) affect the thermal conductivity of alumina based nanofluid. The thermal conductivity values were found using the transient plane source (TPS) method. It was found that mass difference scattering provided the most effective mechanism for reducing the thermal conductivity of the alumina based nanofluid....
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....
Thermal conductivity of heating and cooling fluids with added nanoparticles dubbed 'nanofluids' are used as potential to improve the efficiency of heat transfer fluids using a thermal constants analyser. The Thermal conductivity enhancements of Cu-H2O nanofluids are dependent on the weight fraction of nanoparticles, pH values and sodium dodecylbenzenesulfonate (SDBS) surfactant concentration of nano-suspensions. Combining both the pH and chemical surfactant is recommended to improve the thermal conductivity for ...
