The thermal conductivity, viscosity, and stability of nanofluids were evaluated to determine how varying experimental conditions can affect these properties. It was determined that increasing the concentration, temperature, and time spent sonicating the nanofluids can increase the thermal conductivity, while the addition of alcohol caused ...
Using Al2O3 nanoparticles, de-ionized water, and different volume fractions of two surfactants, Al2O3/water nanofluids were prepared by a two-step method. Thermal conductivities of the nanofluids were measured by the thermal constants analyzer. The choice of surfactant used (either sodium dodecyl sulfate (SDS) ...
