RETRACTED: Numerical simulation of nanofluid forced convection heat transfer improvement in existence of magnetic field using lattice Boltzmann method

Abstract

In this paper, nanofluid forced convection heat transfer is investigated in existence of magnetic field. Three dimensional simulations are presented by means of Lattice Boltzmann Method. Koo-Kleinstreuer-Li (KKL) model is considered to estimate the properties of nanofluid. Roles of Hartmann number, Reynolds number, Al2O3 volume fraction are illustrated graphically. Outputs are depicted in forms of velocity, isokinetic energy, streamlines, isotherms contours and Nusselt number. Results demonstrate that velocity of nanofluid augments with rise of Reynolds number and Al2O3 volume fraction but it reduces with increase of Hartmann number. Convection mode reduces with enhance of Lorentz forces. Temperature gradient over the moving wall augments with augment of hot surface velocity and Al2O3 volume fraction.
