Mass transfer in MHD flow of alumina water nanofluid over a flat plate under slip conditions

Abstract

Present paper deals with analysis of mass transfer in two dimensional magnetohydrodynamic (MHD) slip flow of an incompressible, electrically conducting, viscous and steady flow of alumina water nanofluid in the presence of magnetic field over a flat plate. The governing equations representing flow are transformed into a set of simultaneous ordinary differential equations by using appropriate similarity transformation. The set of equations thus obtained has been solved using adaptive Runge–Kutta method with shooting technique. The effects of solutal Grashof number and Schmidt number on velocity distribution profile, concentration profile, shear stress and concentration gradient have depicted graphically and analyzed. It is found that the concentration increases and concentration gradient decreases with increasing value of solutal Grashof number. Also, the concentration decreases with an increase in Schmidt number.
