The effects of MHD on the nanofluid flow of mixed convection of a steady laminar boundary layer over a vertical flat plate embedded in a saturated porous medium with Soret and Dufour and chemical reaction. The homogeneous chemical reaction of first order is taken into account. The simultaneous variations of heat and mass transfer also influenced with mixed convection and chemical reaction along with double diffusion. The governing partial differential equations are converted into ordinary differential equations by similarity transformations. The coupled nonlinear ordinary differential equations are linearized by Quasi-linearization technique. The linear ordinary differential equations are solved by using implicit finite difference scheme with the help of C-programming. Numerical calculations are carried out for different values of dimensionless parameter and an analysis of the results obtained shows that the flow field is influenced appreciably by the magnetic parameter M, buoyancy ratio parameter N, Soret number Sr, Dufour number Df, radiation R, chemical reaction δ, mixed convection parameter Ra/Pe, Brownian motion parameter Nb, Thermophoresis parameter Nt, Lewis number Le and Prandtl number Pr and heat and mass transfer.
