| description | In order to maximize the efficacy of multiple component electronic systems or photovoltaic panels in multiple arrangements, thermal management and cooling system design become crucial. In the present work, a novel cooling system with U-shaped cooling channel for a triple conductive panel system is considered under ternary nano-enhanced magnetic field effects while Galerkin weighed residual finite element method is used as the solution technique. The numerical investigation is carried out for various Hartmann numbers (Ha between 0 and 60), magnetic field inclination (between 0 and 90), side wall inclination of cooling cavity (between 0 and 30), and cavity expansion ratio (between 0.2 and 0.5). At the highest Ha value, panel Pn2 shows a temperature reduction of 52 °C for η=0, and an increase of roughly 24 °C for η=30. The best magnetic field inclination for the lowest surface temperature varies according to the panels and cooling channels used. The surface temperature variation is 2 °C, 114 °C, and 114 °C for panels Pn1, Pn2, and Pn3, when comparing the best and worst cases. As expansion ratios increase, the average Nu generally drops in cooling channels with both flat (η=0) and inclined (η=30) walls. Based on the first three objectives by using optimization with COBYLA, panels Pn1, Pn2, and Pn3 have minimum temperatures of 30.3 °C, 46.6 °C, and 41.4 °C, respectively. By utilizing different objectives, different panel surface temperatures and performance improvements are achieved. |
