Bottom Line: This article covers recent advances in the last decade by researchers in both pool boiling and convective boiling applications, with nanofluids as the working fluid.Conflicting data have been presented in the literature on the effect that nanofluids have on the boiling heat-transfer coefficient; however, almost all researchers have noted an enhancement in the critical heat flux during nanofluid boiling.Several researchers have observed nanoparticle deposition at the heater surface, which they have related back to the critical heat flux enhancement.

ABSTRACT
There has been increasing interest of late in nanofluid boiling and its use in heat transfer enhancement. This article covers recent advances in the last decade by researchers in both pool boiling and convective boiling applications, with nanofluids as the working fluid. The available data in the literature is reviewed in terms of enhancements, and degradations in the nucleate boiling heat transfer and critical heat flux. Conflicting data have been presented in the literature on the effect that nanofluids have on the boiling heat-transfer coefficient; however, almost all researchers have noted an enhancement in the critical heat flux during nanofluid boiling. Several researchers have observed nanoparticle deposition at the heater surface, which they have related back to the critical heat flux enhancement.

Figure 5: TiO2 nanoparticle-coated NiCr wire after pool boiling CHF experiment of nanofluids with different particle volume concentrations [34].

Mentions: CHF enhancement in nanofluids has been widely observed by almost all researchers in convective boiling [17,23,24] and in pool boiling [4,15,17,28-34,36,37,40-42,44,45,47]. On the other hand, the BHT coefficient database is fairly inconsistent, and the data are rather scattered. Some researchers report no change of heat transfer in the nucleate boiling regime, some report heat transfer deterioration, and others heat transfer enhancement. Several studies (Kim et al. [36], Coursey and Kim [40], Kim et al. [34], Ahn et al. [17], Kim et al. [32], to name but a few) have attributed the CHF enhancement seen during both pool and convective boilings of nanofluids to the improved wettability at the heater surface after the deposition of a nanoparticle layer. Figure 5 clearly shows the nanoparticle deposit left on a NiCr wire after pool boiling of TiO2 nanoparticles, taken from Kim et al. [34].
