Kerosene is used as a coolant in engines, however like many conventional heat transfer fluids, it has a low thermal conductivity. Nanofluids are suspensions of thermally conductive nanometer sized particles in a base fluid. This paper explores the thermal properties of a Kerosene based nanofluid with copper oxide (CuO) nanoparticles. The thermal conductivity meter measured the thermal conductivity of copper oxide/Kerosene nanofluids using the transient plane source (TPS) technique. ...
The authors used the transient plane source (TPS) technique to investigate the effect of pH on nanofluid thermal conductivity and viscosity. Cu and Al2O3 nanoparticles were dispersed in water to create two nanofluids. pH was then varied and thermal conductivity and viscosity measurements were made on the nanofluids. An optimal pH was found to give the lowest viscosity and highest thermal conductivity, and a significant improvement in thermal ...
This study aimed to improve the heat transfer capabilities of water-based nanofluids, by varying the concentration of sodium dodecylbenzene sulfonate (SDBS), a chemical surfactant, as well as by altering the pH. It is said that the thermal conductivity and stability of nanofluids are directly related and are also greatly influenced by pH and chemical surfactant concentration. The water-based nanofluids displayed higher thermal conductivity values as the pH and SDBS concentration ...
