Abstract:
This research article aims to investigate the consequences of binary chemical reaction, Soret and Dufour effects on Darcy-Forchheimer nanofluid flow subject to thermal radiation. Stretching surface is taken to drive the fluid along positive horizontal direction. Brownian motion, viscous dissipation and the Thermophoresis are also accounted. The governing system of partial differential equations (PDEs) is transformed into non-linear system of ordinary differential equations (ODEs) using appropriately adjusted transformations. RK45 with shooting method is adopted to solve the system of equations. Graphical approach is used to interpret the results and the values of important physical quantities are given in tabular data form. Velocity field, temperature distribution, concentration distribution is analyzed for variation in respective parameters. Furthermore, density graphs and stream lines are sketched. The outputs indicate that a rise in thermal radiation parameter results in rise of temperature field. A clear decline is noticed in velocity field for elevated values of inertia and porosity factors. The Dufour effect results in rise of temperature distribution and the same is noticed in concentration distribution for rising values of Soret effect. The porosity factor has strong impact on heat transport mechanism.
