Heat transfer enhancement of Al2O3-H2O nanofluids flowing through a micro heat sink with complex structure

Nanofluids are used in heat sink applications to improve the rate of heat dissipation and reduce temperature gradients in electronics. This study specifically examined the thermal properties of Al2O3-H2O nanofluids used in micro heat sinks. An instrument measured the thermal conductivity of the Al2O3-H2O nanofluids using the transient plane source (TPS) method. Results showed that, as expected, thermal conductivity increased with the concentration of ...

Effects of surfactant on the stability and thermal conductivity of Al2O3/de-ionized water nanofluids

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) or polyvinylpyrrolidone (PVP)) had an influence on the thermal and mechanical properties of the nanofluids. PVP was found to be better at stabilizing the nanofluid, ...
