摘要: Abstract This numerical work examines the impact of an external magnetic field on hydrothermal aspects natural convection a power-law non-Newtonian nanofluid inside baffled U-shape enclosure. The enclosure is heated from bottom and cooled baffles while other walls are thermally insulated. Sinusoidal profile chosen to describe temperature distribution along wall. A comprehensive analysis conducted study influence pertinent parameters including Rayleigh number (Ra), Hartmann (Ha), nanoparticle volume fraction (ϕ), aspect ratio cold (AR), inclination angle, index (n) flow heat transfer characteristics in detail by using Galerkin finite element method. obtained results show that n Nusselt (Nu) considerable for Ra=106 inappreciable below this value. Ha significant when smaller than 30. For
