Heat transfer and critical heat flux of nanofluid boiling: A comprehensive review

Nanofluid boiling is an important research area of nanofluids, which provides many opportunities to explore new frontiers but also poses great challenges. This paper presents a comprehensive review on the nanofluid heat transfer (HT) and critical heat flux (CHF) of pool boiling and flow boiling. The research results in the literature previously reviewed are briefly summarized. An emphasis is put on the recent progresses in the nanofluid HT and CHF of pool boiling and flow boiling. It is also included comparing developments and research results of the nanofluid HT and CHF between pool boiling and flow boiling. The important achievements, inconsistence, and contradictions of the existing research results are identified and discussed in detail. Topics worthy of attention for future studies are suggested.
