Optimized framework for Darcy-Forchheimer flow with chemical reaction in the presence of Soret and Dufour effects: A shooting technique.

[Display omitted] • Here Darcy-Forchheimer relation is accounted in flow of viscous fluid. • Soret and Dufour effects are considered. • Chemical reaction is addressed in concentration equation for the mass transfer analysis. • Numerical results are obtained via Shooting method. The main purpose of this work is to analyze chemically reactive Darcy-Forchheimer nanoliquid flow towards a stretched surface. Buongiorno's model is utilized for the nanoliquid importance. Additionally, Soret and Dufour characteristics are also considered. Gyrotactic microorganisms with chemically reactive flow are considered. The given partial differential systems are converted into dimensionless ordinary expressions with the implementation of suitable transformation. Non-dimensional systems are solved through Newton built in-shooting technique. Graphical outcomes for temperature, microorganisms' field, velocity and concentration versus secondary variable are discussed. Numerical outcomes of drag force, density number and heat transport rate for sundry parameters are examined. A reduction occurs in velocity for higher porosity variable. Higher estimation of Dufour number upsurges the temperature. Similar impact for temperature is seen for random motion and thermophoresis variables. Concentration upsurges for higher Soret number, while reverse effect holds for Schmidt number. An increment in heat transport rate occurs for higher Dufour number. Microorganisms' fluid diminishes for higher Peclet number, while reverse impact seen for density number. [ABSTRACT FROM AUTHOR]
