The main objective of this framework is to establish the modeling and simulation of mixed convection flows along with a curved stretching sheet with Sisko fluid. The impacts of thermal radiation and first-order chemical reaction are also incorporated to illustrate the heat and mass transfer phenomenon. In addition, the convective condition is deliberated to discuss the heat transfer mechanism. The normalized conservation equations emerge as a system of non-linear
two-dimensional coupled Partial Differential Equations (PDEs). Under appropriate transformation, these equations are converted into Ordinary Differential Equations (ODEs). Numerical procedures are examined in this study for various active parameters. A significant declining behavior of the velocity profile is depicted with an increase in mixed convection and buoyancy ratio parameter.
An enhancement conduct in the temperature of the fluid is reported through the growing values of radiation parameter and Biot number. A remarkable decreasing trend is addressed by the higher values of the chemical reaction parameter while plotting the concentration profile of the fluid. Moreover, the resistive forces, heat, and mass transfer rates are discussed in tabular form. A comparison with shooting and RK-45 Fehlberg method is illustrated to show the validity of the present scheme. Thus the present consequences are well correlated with the existing literature.
