Pool boiling heat transfer characteristics of Al2O3-Water nanofluids is studied experimentally using a NiCr test wire of 36 SWG diameter. The experimental work mainly concentrated on i) change of Critical Heat Flux(CHF) with different volume concentrations of nanofluid ii) flow visualization of pool boiling using a fixed concentration of nanofluid at different heat flux values. The experimental work revealed an increase in CHF value of around 48% and flow visualization helped in studying the pool boiling behaviour of nanofluid. Out of the various reasons which could affect the CHF enhancement, surface roughness plays a major role in pool boiling heat transfer.
