“…An 88.53% enhancement in the heat transfer coefficient was observed to be achieved by using the hybrid Ag/ZnO nanofluid for a nanoparticle volume fraction of 0.1% and aspect ratio H/D = 3.5 as compared to water. Chen and Cheng [145] performed a numerical investigation to study the heat transfer performance of nanofluid (SiO2-water) jet impingement on a concave target surface having a porous copper metal block. The heat transfer coefficient was enhanced by 5.85% at Reynolds number = 9500 and a nanoparticle concentration of 3% by using the nanofluid as compared to pure water.…”

Jet impingement is considered to be an effective technique to enhance the heat transfer rate, and it finds many applications in the scientific and industrial horizons. The objective of this paper is to summarize heat transfer enhancement through different jet impingement methods and provide a platform for identifying the scope for future work. This study reviews various experimental and numerical studies of jet impingement methods for thermal-hydraulic improvement of heat transfer surfaces. The jet impingement methods considered in the present work include shapes of the target surface, the jet/nozzle–target surface distance, extended jet holes, nanofluids, and the use of phase change materials (PCMs). The present work also includes both single-jet and multiple-jet impingement studies for different industrial applications.

“…Many aspects of nanofluids including preparation, stabilization, material characterization, effective thermo-physical property modeling and applications in different engineering systems have been considered and reviewed in many studies (Esfe et al , 2020, Pordanjani et al , 2019, Afshari et al , 2021, Asadi et al , 2019, Khanlari et al , 2019, Mahian et al , 2021, Özerinç et al , 2010, Ghalambaz et al , 2019). In jet cooling applications, nanofluids have been used and potentials of using nanofluids on the thermal efficiency improvement have been reported (Li et al , 2012, Nguyen et al , 2009, Selimefendigil and Chamkha 2019, Manca et al , 2016, Çiçek and Baytaş 2021, Chen and Cheng 2020, Nimmagadda, Lazarus and Wongwises 2019b.

“…It was noted that many studies were needed to shed some light on the processes because of the uncertainties in the interactions of different parameters and presence of complicated random processes. J-I cooling has been considered with nanofluids by taking into account the nanoparticles shape effects (Shirvani et al , 2021, Selimefendigil and Öztop 2017a), curvature of the cooled surface (Chen and Cheng 2020, Selimefendigil and Öztop 2017b) and non-Newtonian aspects of the nanofluid (Lamraoui et al 2019, Qiang et al , 2018, Yousefi-Lafouraki et al , 2016, Selimefendigil, Oztop and Chamkha 2021b).…”

Purpose The purpose of this study is to analyze the impacts of combined utilization of multi-jet impinging cooling of nanofluids with magnetic field and porous layer on the cooling performance, as effective cooling with impinging jets are obtained for various energy systems, including photovoltaic panels, electronic cooling and many other convective heat transfer applications. Design/methodology/approach Finite element method is used to explore the magnetic field effects with the inclusion of porous layer on the cooling performance efficiency of slot nanojet impingement system. Impacts of pertinent parameters such as Reynolds number (Re between 250 and 1,000), strength of magnetic field (Ha between 0 and 30), permeability of the porous layer (Da between 0.001 and 0.1) on the cooling performance for flat and wavy surface configurations are explored. Findings It is observed that the average Nusselt number (Nu) rises by about 17% and 20.4% for flat and wavy configuration while temperature drop of 4 K is obtained when Re is increased to 1,000 from 250. By using magnetic field at the highest strength, the average Nu rises by about 29% and 7% for flat and wavy cases. Porous layer permeability is an effective way of controlling the cooling performance while up to 44.5% variations in the average Nu is obtained by varying its value. An optimization routine is used to achieve the highest cooling rate while the optimum parameter set is obtained as (Re, Ha, Da, γ, sx) = (1,000, 30, 0.07558, 86.28, 2.585) for flat surface and (Re, Ha, Da, γ, sx) = (1,000, 30, 0.07558, 71.85, 2.329) for wavy surface configurations. Originality/value In thermal systems, cooling system design is important for thermal management of various energy systems, including fuel cells, photovoltaic panels, electronic cooling and many others. Impinging jets are considered as effective way of cooling because of its ability to give higher local heat transfer coefficients. This paper offers novel control tools, such as magnetic field, installation of porous layer and hybrid nano-liquid utilization for control of cooling performance with multiple impinging jets.
