We report the first Critical Heat Flux (CHF) experiment in pool boiling conditions using Fullerene (C60) nanofluids. Fullerene (C-60) nanofluids (0.0001, 0.001, and 0.01 vol.%) were prepared for experiments. We observe that maximum CHF enhancement up to ~108% was observed at volume concentration 0.01% Fullerene (C-60) nanofluids compare to pure waters. The heat transfer coefficient also found enhanced, the boiling curves observed shifted to the right. After experiment we found there was nanoparticle deposited on the heater surface, several investigations have been performed to discover the porous layer on the heater surface. The mechanisms of pool boiling CHF and heat transfer coefficient enhancement using Fullerene (C60) nanofluids also been discussed.
