“…An empirical correlation was developed to predict the heat flux for nucleate pool boiling of nanofluids [104]. The effect of nanorod length on pool boiling heat transfer for water was experimentally studied [105]. The influence of nanoparticles on the pool boiling heat transfer in open-celled foams at atmospheric pressure was investigated [106].…”

This paper reviews the previous work carried on pool boiling heat transfer during heating of various liquids and commodities categorized as refrigerants and dielectric fluids, pure liquids, nanofluids, hydrocarbons and additive mixtures, as well as natural and synthetic colloidal solutions. Nucleate pool boiling is an efficient and effective method of boiling because high heat fluxes are possible with moderate temperature differences. It is characterized by the growth of bubbles on a heated surface. It occurs during boiling of liquids for excess temperature ranging from 5 to 30 °C in various processes related to high vaporization of liquid for specific purposes like sugarcane juice heating for jaggery making, milk heating for khoa making, steam generation, cooling of electronic equipments, refrigeration and etcetera. In this review paper, pool boiling method during heating of liquids for specific purpose is depicted. It is inferred that enhancement in pool boiling heat transfer is a challenging and complex task. Also, recent research and use of various correlations for natural convection pool boiling is reviewed.

Enhancement of subcooled and saturation pool boiling is of interest for many applications. The present study proposes coating heated surface using nanotextured of Cu nanoparticles with carbon nanofibers. This texture formation on copper substrate surface passes through different chemical stages under specific conditions. Using electrospinning, coating was carried out at different times (5, 15, and 30 min). After vacuum drying at 60 oC for 24 h, the copper substrates attaching the electrospun mat were calcined at 850 oC under vacuum. and accordingly, different contact angles were measured as 80o, 115o, and 102o. The coated surfaces are coded by S1, S2 and S3 for the electrospun coated surfaces of (5, 15, and 30), respectively.All nanostructured coated surfaces showed a good heat transfer enhancement compared to uncoated copper surface for both HTC and CHF. The results showed an enhancement of HTC by 57.83%, 40.3% for S2 and S3 respectively and an enhancement of CHF by 13.67%, 17.11% and 48.14% for S1, S2 and S3 respectively.

“…Organic and inorganic phase change materials have obtained extensive attention in recent years due to their higher latent heat, suitable phase‐transition temperature, and stable physical and chemical properties . The use of newly developed materials or structures combined with pool boiling to increase heat transfer developing, and nano‐surface can significantly improve the boiling heat transfer effect . Different oxide materials such as as alumina, titania, silica, zinc oxide and CuO have been used as a functional surface of the coating .…”

A titanium plate with titanium dioxide nanotube was prepared with the anodic oxidation process. The heat transfer through this plate was studied with quantitative heptanol solution as self-rewetting solution. The microstructure of this nano-structure surface was characterized by SEM and the surface tension of the self-rewetting solution on it was measured by the static contact angle. The results indicated that the heat transfer coefficient (HTC) and the critical heat flux (CHF) were significantly improved with the increasing concentration of heptanol. In the 0.1 mass% heptanol solution, the best heat transfer enhancement effect was obtained. The HTC is 22.46 kW Á m À2 Á K À1 and CHF is 536.64 kW Á m À2 , which were increased by 121 and 62.9 % more than those in the distilled water. According to the experimental phenomenon and mechanism analysis, the surface of the nanotube has a more effective vaporization core, greater roughness, and better wettability. Combined with the special double surface tension gradient characteristic of the self-wetting solution, the hot and cold liquid forms a microcirculation and the synergistic superposition of the driving force strengthens. The system can produce tiny and fine bubbles under low superheat, detach quickly, transfer heat quickly, and perform secondary wetting in time to achieve synergistic enhanced boiling heat transfer.
