“…They identified the heat transfer deterioration by the fouled heater surface. Kim et al [6,7] noted that the change of boiling heat transfer coefficient and CHF could be attributed to the surface deposition effects of nanoparticles. A thin deposition layer on the heater surface altered the active nucleation sites and introduced an additional thermal resistance.…”

“…Bi et al, 2011 reported that nanorefrigerant application in a domestic refrigerator resulted in energy consumption reduction as well as in freezing velocity increase. The development of stable nanofluids for use in water-cooled nuclear systems could result in a significant improvement of their economic performance and/or safety margins (Hadad et al, 2010;Kim et al, 2010).…”

Experimental investigation of heat transfer during pool boiling of two nanofluids, i.e. water-Al 2 O 3 and water-Cu has been carried out. Nanoparticles were tested at the concentration of 0.01%, 0.1%, and 1% by weight. The horizontal smooth stainless steel tubes having 10 mm OD and 0.6 mm wall thickness formed the test heater. The experiments have been performed to establish the influence of nanofluids concentration on heat transfer characteristics during boiling at different absolute operating pressure values, i.e. 200 kPa, ca. 100 kPa (atmospheric pressure) and 10 kPa. It was established that independent of nanoparticle materials (Al 2 O 3 and Cu) and their concentration, an increase of operating pressure enhances heat transfer. Generally, independent of operating pressure, sub-and atmospheric pressure, and overpressure, an increase of nanoparticle concentration caused heat transfer augmentation.

A boiling heat transfer is used in various industry such as power generation systems, heat exchangers, air-conditioning and refrigerations. In the boiling heat transfer system, the critical heat flux (CHF) is the important factor, and it indicated safety of the system. It has kept up studies on the CHF enhancement. Recently, it is reported the CHF enhancement, when working fluid used the nanofluid with high thermal properties. But it could be occurred nanoflouling phenomenon from nanoparticle deposition, when nanofluid applied the heat transfer system. And, it is reported that the safety and thermal efficiency of heat transfer system could decrease. Therefore, it is compared and analyzed to the CHF and the boiling heat transfer coefficient on effect of artificial nanofouling (coating) in oxidized multi-wall carbon nanotube nanofluids. As the result, the CHF of oxidized multi-wall carbon nanofluids and the CHF of artificial nanofouling in the nanofluids increased to maximum 99.2%, 120.88%, respectively. A boiling heat transfer coefficient in nanofluid increased to maximum 24.29% higher than purewater, but artificial nanofouling decreased to maximum -7.96%.
