“…A variety of materials, such as Al 2 O 3 , TiO 2 , ZnO, Ag, Au, SiC, and carbon allotropes, have been studied as part of efforts to enhance BHT and CHF. Most of the studies conducted on this subject have reported that enhanced heat transfer and CHF depend on nanoparticle deposition during boiling [2][3][4][5]. In comparisons of surface coating technologies and nanofluid techniques, such as the deposition of particles on heating surfaces, the use of nanowires, and the use of thin film coatings on substrates, nanotechnology has been widely investigated in boiling experiments to develop more desirable effective heat transfer methods [6].…”

“…Stability of nanofluids is considered as a critical issue when working with such new thermal fluids, many researchers studied this issue, and they reported the most important factors that could influence the stability of nanofluids such as nanoparticles types, size, concentration and preparation methods. Nanoparticles should be dispersed good enough in order to avoid the agglomeration within the suspensions by applying different techniques such as ultrasonication, additive stabilizer and pH control [84,85]. Figure 16 illustrates the methods and techniques used in the literature to measure and enhance the stability of nanofluids.…”

Flow boiling heat transfer widely utilized in numerous industrial applications such as boiler tubes, evaporators and cooling of reactors in a nuclear power plant. Nanofluids are a new category of thermal fluids, made by dispersing a nanometer solid particle which is usually less than 100 nm into conventional liquids such as water, oil engine and ethylene glycol with the intent to enhance the thermal properties of the base fluids. This work reviews the recent experimental studies focusing on the flow boiling heat transfer using nanofluids. The latest results associated with this subject are presented and outlined to account the influence of several parameters, which are related to operating conditions and nanoparticles morphology on the heat transfer coefficient and the critical heat flux. Besides, the effects of nanoparticles on other related sub-phenomenon of the flow boiling by using nanofluids were discussed. Moreover, the latest review papers of the related topic were presented and briefly discussed. Finally, suggestions for future research activities related to this field were also concisely listed.

“…Several studies on CHF with various nanofluids under different test conditions have been conducted in various channels. These covers the low pressure and low flow conditions [128,129], the effect of micro/nanoscale structures on CHF [130], flow boiling in downward-facing channels [131], CHF with magnetic nanofluids [132] and magnetic field effect on CHF with ferrofluid in annulus [133]. In general, CHF enhancement has been achieved but understanding the mechanisms is quite different and this needs to be further In recent years, several studies were conducted to investigate the flow boiling heat transfer and CHF behaviors with nanofluids in mini-and micro-channels [134][135][136][137][138][139][140][141][142].…”

This paper presents a comprehensive and critical review of studies on nucleate pool boiling heat transfer, flow boiling heat transfer, critical heat flux (CHF) and two-phase flow phenomena with nanofluids. First, general analysis of the available studies on the relevant topics is presented. Then, studies of physical properties of nanofluids are discussed. Next, boiling heat transfer, CHF phenomena and the relevant physical mechanisms are explored. Finally, future research needs have been 2 identified according to the review and analysis. As the first priority, the physical properties of nanofluids have a significant effect on the boiling and CHF characteristics but the lack of the accurate knowledge of the physical properties has greatly limited the studies. Fundamentals of boiling heat transfer and CHF phenomena with Nanofluids have not yet been well understood. Flow regimes are important in understanding the boiling and CHF phenomena and should be focused on. Two phase pressure drops of nanofluids should also be studies. Furthermore, economic evaluation of the enhancement technology with nanofluid should be considered for the new heat transfer enhancement technology with nanofluids. Finally, applied research should be targeted to achieve an enabling practical heat transfer and CHF enhancement technology for engineering application with nanofluids.
