Quenching experiment on vertical surface using Carbon Nanotube (CNT) nanofluids were conducted to see the effect of using CNT nanofluids on the quenching speed. Homogeneous and stable CNT nanofluids have been produced by suspending well dispersible CNT nano-particle into water base fluid. CNT nanofluids (0.0001 vol.% and 0.01 vol.%) were prepared for experiments. From zeta potential results our CNT 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 CNT nanofluids enhanced compare to water.
