Boiling heat transfer of nanofluids: The effect of heating surface modification

This work reports a comparative study of nucleate boiling heat transfer with aqueous alumina nanofluids on two specially designed surfaces. The detailed surface characterization before and after boiling reveals that the modification of heating surface geometries is mainly responsible for many contradictory results reported in literature. The enhancement or deterioration of boiling heat transfer by nanofluids is dependent upon different surface...
