ABSTRACT
More attention to the thermal conductivities of nanofluids than to the resulting heat transfer characteristics has been paid over the past few years. The use of nanofluids appears promising in several aspects of twophase flow and heat transfer, but still faces several challenges: (1) the lack of agreement between experimental results from different research groups and (2) the lack of theoretical understanding of the underlying mechanisms with respect to nanoparticles. Thus, it is essential to review the state-of-the art review on nanofluid two-phase flow and heat transfer, including nucleate pool boiling, flow boiling, and CHF, and to identify the future research needs, which are the purposes of this chapter.
