Impact of chemical reaction on magnetohydrodynamics non-Darcian mixed convective nanofluid flow past over a stretching sheet with non-uniform heat source/sink

The present study is to examine the consequences of free-forced convective heat-mass transportation and chemical reaction on non-Darcy, MHD, incompressible nanofluid fluid flow through an extended lamina, immersed in a permeable medium along with an external constant magnetic and electrical field. The fluid flow governing equations (PDEs) has been converted into an equivalent system of nonlinear ODEs by applying appropriate similarity transformation, and then solved numerically with the help of SQLM (Spectral quasilinearization method). The significant Fluid parameters such as Hartman number, Buoyancy parameter, Prandtl number, and chemical reaction parameter are examined graphically and also numerically. The graphical representation shows that the Hartman number, Brownian motion parameter, Schmidt number, and chemical reaction parameter decline in velocity. In the vicinity of the stretching lamina, the Brinkman number and Hartman number reduce the Bejan number. However, the influence of the Brinkman number and Hartman number is negligible far away from the lamina. On the other hand, thermal layouts, concentration layouts, and entropy generation are enhanced with the increment in the Hartman number. For the engineering interest the coefficients of the Skin-friction, Nusselt number, and Sherwood number are evaluated numerically.
