Original abstract

The primary goal of this study is to investigate the impact of SiO 2 -Fe 3 O 4 hybrid nanofluid flow on thermal performance as it passes through a circular cylinder and an octagonal cavity. There are several rectangular, heated fins on the inside of the hot cylinder. The effects of a uniform magnetic field, Darcy–Forchheimer porous resistance, and internal fin structures on heat transfer characteristics are examined, with a focus on thermal energy storage. The advanced Yamada–Ota and Xue models, which enhance heat transfer rates more effectively, are examined, and their outcomes are compared with those of previous research. The control volume finite element method (CVFEM) has been employed to numerically solve the governing equations. The present simulation captures these trends, with a notable 52.25% improvement in the local Nusselt number observed with the advanced Yamada thermal conductivity model. The artificial neural network has been used, which supports the simulation of the results obtained.
