Abstract
This research focuses on entropy generation rate per unit volume in magneto-hydrodynamic (MHD) mixed convection boundary layer flow of a viscous fluid over an inclined stretching sheet. Analysis has been performed in the presence of viscous dissipation and non-isothermal boundary conditions. The governing boundary layer equations are transformed into ordinary differential equations by an appropriate similarity transformation. The transformed coupled nonlinear ordinary differential equations are then solved numerically by a shooting technique along with the Runge-Kutta method. Expressions for entropy generation (Ns) and Bejan number (Be) in the form of dimensionless variables are also obtained. Impact of various physical parameters on the quantities of interest is seen.
Highlights
Hydromagnetic (MHD) boundary layer flow over a stretching surface has vital importance because of its ever-increasing usage in industrial applications such as the production of paper, glassware, cable coatings, fabrication of adhesive tapes, artificial fibers, metal spinning, roofing shingles, fine-fiber mats, and metallic plates to mention a few among others

While a decreasing effect has been observed with the variation of thermal of thermal convective parameter and Prandtl number
Summary
Hydromagnetic (MHD) boundary layer flow over a stretching surface has vital importance because of its ever-increasing usage in industrial applications such as the production of paper, glassware, cable coatings, fabrication of adhesive tapes, artificial fibers, metal spinning, roofing shingles, fine-fiber mats, and metallic plates to mention a few among others. In all such technological processes, the kinematics of stretching and heat transfer have a significant impact in the improvement of final product quality through control of the rate of cooling. Motivated by the abovementioned facts, the present research has been undertaken to perform an irreversibility analysis of MHD mixed convection flow over an inclined stretching sheet
