Using Micropolar Nanofluid under a Magnetic Field to Enhance Natural Convective Heat Transfer around a Spherical Body

An analysis is discussed of the heat and mass transfer for micropolar nanofluid in presence natural convection from a spherical body with magneto-hydrodynamic (MHD) effects. The constant wall temperature boundary condition also studied. By employing proper similarity transformations, governing equations are converted into set partial differential (PDEs) used conditions, which can then be solved numerically via efficient Keller-box implicit numerical finite difference method. results impacts controlling parameters on physical quantities have been presented, tabular graphically, by MATLAB symbolic software. Comparisons current study to previously published show good agreement, indicating that our computations legitimate accurate. Increasing nanoparticle volume fraction observed depress local skin friction, Nusselt number, angular velocity while reverse effects temperature.
