Seven distinct samples of nanofluids consisting of different concentrations of spherical graphitized carbon black in an ethylene glycol solution were analyzed to determine their thermal and rheological behavior. The thermal conductivity measurements were made at 20°C and 30°C with a transient hot wire instrument made by Thermtest called THW-L2 and specifically designed to measure the thermal conductivity of liquids. This study was ...
Nanofluids are relatively new materials that are composed of liquids containing solid nanoparticles ranging from 1-100 nm. This study examined the thermal conductivity of Al2O3 (aluminum oxide)-H2O nanofluids in water under multiple pH and sodium dodecylbenzenesulfonate (SDBS) conditions. A transient plane source (TPS) was used to measure the thermal conductivities of the samples. It was found that when the pH of the nanofluid reached approximately 8.0, the solution ...
