### ABSTRACT

A numerical study of two-dimensional magnetohydrodynamic (MHD) boundary layer flow of viscous nanofluid over a stretching sheet is developed. Fluid-saturating porous space is bounded by a stretching surface. The Darcy–Forchheimer model is employed to characterize the porous medium. A uniform transverse magnetic field is applied perpendicular to the surface of the sheet. Appropriate transformations are employed in obtaining the nonlinear ordinary differential equations. Convective boundary condition and normal flux of the nanoparticles are implemented at the surface of the sheet. Numerical solutions for the velocity, temperature, and concentration fields are constructed. The results are presented and discussed through graphical and tabular forms.
