Reflooding experiment on vertical surface using Al203 nanofluids were conducted to see the effect of using Al203 nanofluids on the quenching speed. Homogeneous and stable nanofluids have been produced by suspending well dispersible Al203 nano-particle into water base fluid. Al203 nanofluids (0.0001 vol.% and 0.01 vol.%) were prepared for experiments. From zeta potential results our Al203 nano-fluids has a good stability. The test section was an annular channel with a concentric inner rod made of stainless steel SUS316 and an outer tube made of quartz glass. The experimental data obtained show that quenching speed using nanofluids enhanced compare to water.
