“…Choi 20 first made these modern fluids and called them NFs. After the introduction of NFs and their amazing thermal properties, much research was done on their performance in diverse applications such as thermal management of electronic components 21 , 22 and photovoltaic panels 23 , 24 , nuclear applications 25 , 26 , and performance improvement of solar thermal collectors 27 – 29 , heat exchangers 30 – 32 and car radiators 33 – 35 . The literature inspection shows that the performance of thermal systems with NF coolants equipped with turbulators was investigated by various researchers.…”

This study is devoted to the numerical assessment of the influence of helical baffle on the hydrothermal aspects and irreversibility behavior of the turbulent forced convection flow of water-CuO nanofluid (NF) inside a hairpin heat exchanger with 100 mm length, 10 mm inner tube internal diameter, and 15 mm outer diameter internal diameter. The variations of the first-law and second-law performance metrics are investigated in terms of Reynolds number (Re = 5000–10,000), volume concentration of NF ($$\varphi =0-4\mathrm{\%}$$ φ = 0 - 4 % ) and baffle pitch (B = 25–100 mm). The results show that the NF Nusselt number grows with the rise of both the Re and $$\varphi$$ φ whereas it declines with the rise of B. In addition, the outcomes depicted that the rise of both Re and $$\varphi$$ φ results in the rise of pressure drop, while it declines with the increase of B. Moreover, it was found that the best thermal performance of NF is equal to 1.067, which belongs to the case B = 33.3 mm, $$\varphi$$ φ =2%, and Re = 10,000. Furthermore, it was shown that irreversibilities due to fluid friction and heat transfer augment with the rise of Re while the rise of B results in the decrease of frictional irreversibilities. Finally, the outcomes revealed that with the rise of B, the heat transfer irreversibilities first intensify and then diminish.

“…The results showed that the MWCNT-CuO/H2O nanofluid exhibited a lower pressure drop than the CuO/water fluid. The effectiveness of Al2O3-CuO/water hybrid nanofluid was explored by Zhang et al, 18 while Abbas et al 19 studied the possibility of Fe2O3-TiO2/water hybrid nanofluid. Both groups found promising results.…”

Heat transfer is critical due to its broad application in a variety of industries. New hybrid nanofluids are being used to improve the heat transfer competencies of ordinary fluids and have an enormous exponent heat than nanofluids. Hybrid nanofluids, a novel form of nanofluid, are being utilized to improve the heat transfer capacities of regular fluids and have a more outstanding heat exponent than nanofluids. Two-element nanoparticles submerged in a base fluid make up the hybrid nanofluids. Flow and heat transport properties of a hybrid nanofluid across a slick surface are studied in this study. Nanoparticle shape analysis, porous media, thermal conductance variations, and thermal radiative effects are all part of the process. A numerical approach called the Keller box method is used to solve the governing equations numerically. EO-Engine Oil has been used as a rich, viscous base fluid in this study, and a Cason hybrid nanofluid was examined. This fluid contains two diverse forms of nanoparticles: Copper (Cu) and Magnesium Zinc Zirconium alloy (MgZn6Zr). Compared to standard Cu-EO nanofluids, the heat transmission level of such a fluid (MgZn6Zr-Cu/EO) has steadily increased, which is an important finding from this study. The boundary-lamina-shaped layer's components have the highest thermal conductivity, while sphere-shaped nanoparticles have the lowest. When nanoparticles are assimilated, the entropy of the system increases by a factor of three: their ratio by fractional size, their radiative properties, and their thermal conductivity variations.

In the present research, a comprehensive analytical framework is proposed for optimal sizing of louvered fin flat tube car radiators. In order to perform optimal sizing, eleven geometric variables, which are all geometric parameters of the radiator, were selected as the design parameters. These variables include large and small diameters of tubes, length and wall thickness of tubes, fins’ pitch, louvers’ pitch on each fin, length of the fin, louver length and height, fin thickness, number of fins and louver angle on fins. The effects of all of these parameters on the cooling capacity and total weight of the radiator are investigated in the form of single objective optimization problems in which cooling capacity should be maximized and total weight of the radiator should be minimized. Using the proposed framework, the cooling capacity of the radiator has increased by about 8.8% compared to the base design. It is shown that some geometric parameters have the opposite effect on objective functions. Therefore, an analytical multi-objective optimization procedure is proposed to satisfy both of the goals, simultaneously. The values of the geometric parameters determined in this paper are more practical in terms of manufacturing than the values suggested in the base design.
