Abstract
This research article aims to investigate the consequences of binary chemical reaction, thermal radiation, and Soret–Dufour effects on a steady incompressible Darcy–Forchheimer flow of nanofluids. Stretching surface is assumed to drive the fluid along positive horizontal direction. Brownian motion, and the Thermophoresis are accounted in particular. The governing highly nonlinear system of problems which are advanced version of Navier–Stokes equations are transformed into ordinary differential equations (ODEs) using appropriately adjusted transformations invoking symmetric property of the independent variables. The numerical approach using RK45 in connection with shooting technique is adopted to solve the final 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 and concentration distribution are graphically analyzed for variation in respective fluid parameters. Furthermore, density graphs and stream lines are sketched for the present model. The outputs indicate a rise of temperature field in connection with thermal radiation parameter. A clear decline is noticed in velocity field for elevated values of Forchheimer number and porosity factor. The Dufour effect anticipates a rising factor for temperature distribution and the same is noticed for concentration distribution in lieu of Soret effect. Thermal radiation and binary chemical reaction has strong impact on heat transport mechanism. The results for physical quantities such as skin friction, heat and mass flux rates are given in tabular data form in last section of this study.
Highlights
Coined by Choi [1], the advent of nanofluids drastically improved the heat transport efficiency of various fluids especially water and glycol
Such equipment and machinery become heated while working with the typical base fluids; the invention of nanofluids especially those manufactured with most suited metallic ingredients have drastically controlled the heating situation of machinery
The major contribution comes from Soret–Dufour effects and binary chemical reaction which are the novel factors in this study
Summary
Coined by Choi [1], the advent of nanofluids drastically improved the heat transport efficiency of various fluids especially water and glycol. Symmetry 2020, 12, 1421 for nanofluids is typically based on the logic that classic fluids have deficient performing capacity due to low thermophysical properties whereas, the technological development has greatly advanced the machinery and other equipment. Such equipment and machinery become heated while working with the typical base fluids; the invention of nanofluids especially those manufactured with most suited metallic ingredients have drastically controlled the heating situation of machinery.
