文摘

Thermo-physical properties of Al2O3 nanofluid are measured in various base mixture. Experiments are undertaken with Al2O3 nanofluid up to 1% volume concentration. The mixture of 60:40 has the best heat transfer performance with 24.6% enhancement. The friction factor of Al2O3 nanofluids slightly increased with concentration. The heat transfer influenced by concentration, temperature and base ratio.
