![]() ![]() They examined the effect of the magnetic flux on heat transfer efficiency. 9 studied the free convection of the alumina-water nanofluid in a cavity. Additionally, the focus of the research was on the mechanism of nanofluid heat transfer 1, 2, 3, 4, 5, 6, 7, 8. Such as Boilers and cooling systems, thermal energy, and several engineering applications. In recent years, the natural conjugate heat transfer magnetohydrodynamics (MHD) has been an inspiring topic for researchers due to its wide use in various sectors. Also, the rotational speed in a positive direction has a favorable influence on the heat transfer dispersion across the cavity. ![]() Whilst, the porosity presents a minimal impact. The main results proved that increment of Rayleigh number and Darcy number enhances heat transfer convection within the enclosure. The calculations are carried out based on the Galerkin Finite element method (GFEM) to present the streamlines, isotherms, entropy generation, and average Nusselt numbers in details. Likewise, the rotational speed of the cylinder ( \(- 4000 \le \omega \le 4000\)), as well as several characteristics related to the porous layer, are examined li its porosity ( \(0.2 \le \varepsilon \le 0.8\)), Darcy number ( \(- 100000 \le Da \le - 100\)) which indicates the porous medium permeability and the number of undulations ( \(0 \le N \le 4\)). The various thermo-physical parameters are investigated such as Rayleigh number ( \(100 \le Ra \le 100000\)), Hartmann number ( \(0 \le Ha \le 100\)), and the nanoparticles concentration ( \(0.02 \le \phi \le 0.08\)). The current article aims to discuss the natural convection heat transfer of Ag/Al 2O 3-water hybrid filled in an enclosure subjected to a uniform magnetic field and provided with a rotating cylinder and an inner undulated porous layer. ![]()
