Abstract
In this paper, the influence of induced magnetic field on free convection of Al2O3-water nanofluid on permeable plate by means of Koo-Kleinstreuer-Li (KKL) model is reported. Impact of Brownian motion, along with the properties of nanofluid, are also taken into account. The resulting equations are solved utilizing Runge-Kutta integration method. Obtained results are examined for innumerable energetic parameters, namely Al2O3 volume fraction, suction parameter, and Hartmann and magnetic Prandtl numbers. Results indicate that the velocity profile reduces with rise of the suction parameter and magnetic Prandtl and Hartmann numbers but it increases with addition of nanoparticles. Shear stress enhances with rise of suction parameter, magnetic Prandtl and Hartmann numbers. Temperature gradient improves with augment of suction parameter.
Highlights
Magnetohydrodynamic (MHD) free convection has several applications, such as combustion modeling, geophysics, fire engineering, etc
MHD nanofluid natural convection in a tilted wavy cavity has been presented by Sheremet et al [1]
They illustrated that a change of titled angle causes convective heat transfer to be enhanced. 3D MHD free convective heat transfer was examined by Sheikholeslami and Ellahi [2] using Lattice Boltzmann method (LBM)
Summary
Magnetohydrodynamic (MHD) free convection has several applications, such as combustion modeling, geophysics, fire engineering, etc. 3D MHD free convective heat transfer was examined by Sheikholeslami and Ellahi [2] using Lattice Boltzmann method (LBM). Utilized LBM to study Fe3 O4 -water flow, with the aim of drug delivery They concluded that the velocity gradient reduces with the rise of magnetic number. The influence of non-uniform Lorentz forces on nanofluid flow style has been studied by Sheikholeslami Kandelousi [5] He concluded that improvement in heat transfer reduces with rise of Kelvin forces. The influence of Lorentz forces on forced convective heat transfer has been examined by Sheikholeslami et al [11] They illustrated that a greater Reynolds number has a more sensible effect on Kelvin forces. The impacts of the suction parameter, magnetic Prandtl and Hartmann numbers, volume fraction of nanofluid on temperature, and induced magnetic, velocity and current density profiles are examined
