Experimental investigation on pool boiling heat transfer of ZnO, and CuO water-based nanofluids and effect of surfactant on heat transfer coefficient

Thermal behavior of aqueous iron oxide nano-fluid as a coolant on a flat disc heater under the pool boiling condition

“…The interesting point of this study is related to this fact that during the fouling formation on the surface, the heat transfer coefficient does not change over the time, which means that the iron oxide fouling has no significant impact on the boiling thermal performance of nano-fluid. All the findings in this work are in a good a good agreement with those of obtained in previous publications [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42] and this work is regarded as a confirmation for our previous works. …”

“…At high heat flux region, bubbles are formed Influence of heat flux on heat transfer coefficient of water and Iron oxide nano-fluids. Noticeably, the data belonging to natural convection region has not been plotted due to data overlapping and therefore, due to the bubble interactions and bubble transport, the rate of heat transfer significantly increases [28][29][30]. Overall, with increasing the heat flux, heat transfer coefficient considerably improves, which is due to the bubble sub-phenomena.…”

A comprehensive review on pool boiling of nanofluids

“…This layer decreased the contact angle and led to the increase in CHF. Shoghl and Bahrami [49] studied the boiling performance of CuO and ZnO nanofluids with or without surfactant on a rod heater in an SS vessel (37 L). The results demonstrated that the nanofluids without surfactant caused a decrease in the boiling performance with nanoparticle concentrations, making the surface smoother than clean heater.…”

The Investigation of Effects of Temperature and Nanoparticles Volume Fraction on the Viscosity of Copper Oxide-ethylene Glycol Nanofluids

“…In previous researches, the effect of adding different nanoparticles to ethylene glycol has been studied such as Al2O3 nanoparticles [12,13], ZnO [14], and UDD (Ultra Dispersed Diamond) [15]. One of the nanoparticles used in different researches is copper oxide [16][17][18][19][20][21]. Some researchers have been conducted on CuO/EG nanofluid so far.…”
