Single and double impinging jets heat transfer of non-Newtonian power law nanofluid on a partly curved surface under the inclined magnetic field effects is analyzed with finite element method. The numerical work is performed for various values of Reynolds number (Re, between 100 and 300), Hartmann number (Ha, between 0 and 10), magnetic field inclination (γ, between 0 and 90), curved wall aspect ratio (AR, between 01. and 1.2), power law index (n, between 0.8 and 1.2), nanoparticle volume fraction (ϕ, between 0 and 0.04) and particle size in nm (dp, between 20 and 80). The amount of rise in average Nusselt (Nu) number with Re number depends upon the power law index while the discrepancy between the Newtonian fluid case becomes higher with higher values of power law indices. As compared to case with n = 1, discrepancy in the average Nu number are obtained as −38% and 71.5% for cases with n = 0.8 and n = 1.2. The magnetic field strength and inclination can be used to control the size and number or vortices. As magnetic field is imposed at the higher strength, the average Nu reduces by about 26.6% and 7.5% for single and double jets with n greater than 1 while it increases by about 4.78% and 12.58% with n less than 1. The inclination of magnetic field also plays an important role on the amount of enhancement in the average Nu number for different n values. The aspect ratio of the curved wall affects the flow field slightly while the average Nu variation becomes 5%. Average Nu number increases with higher solid particle volume fraction and with smaller particle size. At the highest particle size, it is increased by about 14%. There is 7% variation in the average Nu number when cases with lowest and highest particle size are compared. Finally, convective heat transfer performance modeling with four inputs and one output is successfully obtained by using Adaptive Neuro-Fuzzy Interface System (ANFIS) which provides fast and accurate prediction results.

“…Thin-film solar panels are no longer available in most countries because of their higher cost and lower efficiency (11%) than contemporary mono and polysilicon panels. Bahaidarah [30] utilized monocrystalline solar cells; Alghamdi et al used polycrystalline solar cells [29,31]; and Abou-Ziyan et al [32,33] used multi-junction solar cells in this research.…”

Jet impingement cooling has been utilized to improve the performance of solar energy technologies such as solar collectors, PV systems, PVT systems, and CPV systems. This article provides an overview of current PVT systems using jet impingement. The distinctions between each study, such as research results and PVT system design, are examined and contrasted. The summary demonstrates that solar collectors are the most widely utilized solar energy technology owing to their direct manufacture. There are 20 solar collector studies, 5 for photovoltaic, 9 for photovoltaic thermal, and 8 for concentrator photovoltaic. Geometric characteristics such as jet diameter, spacing, and nozzle height are critical for maximum performance. Furthermore, numerous kinds of coolant jets, such as air, water, and nanofluid, may be seen from the overview. Hybrid systems, such as PVT or CPVT systems, perform better since they create thermal and electrical energy. As a result, more research into developing the hybrid system is advised.

Attention to photovoltaic (PV) cells to convert solar irradiation into electricity is significantly growing for domestic usage and large-scale projects such as solar farms. However, PV efficiency decreases on hot days. This paper proposes an effective cooling technique consisting of a 2% nano encapsulated phase change material (NEPCM) slurry and impinging jets (IJs) in a PV system. The impact of five influencing parameters on PV efficiency is studied using a multi-phase volume of fluid (VOF) model encompassing the effects of solar irradiation, latent heat, mass flow rate, number of nozzles, and jet-to-surface distance. The maximum efficiency of 15.82% is achieved under irradiation of 600 W/m2. The latent heat shows a slight improvement at the low particle concentration. Increasing the mass flow rate to 0.12 kg/s enhances the PV output power by 17.32%. While the PV performance is shown to be improved over the increment of the number of nozzles, the jet-to-surface spacing of 5.1 mm records a remarkable PV surface temperature reduction to 33.8 °C, which is the ideal operating temperature for the PV panel.
