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 ...
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 ...
