Abstract
The basic aim of this work is to examine the activation energy, thermal radiation, and the Joule heating influence in an incompressible two-dimensional dissipative stagnation point flow of a nano liquid past a curved stretching sheet. Furthermore, this work includes the investigation of entropy generation with cross-diffusion. The basic partial differential equations (PDEs) arising from the current study have been converted into ordinary differential equations (ODEs) by applying some dimensionless transformations. The solver bvp4c has been used for the numerical solutions of resulting ODEs. Various graphical results for the velocity, skin friction coefficient, temperature, Nusselt number, concentration, and Sherwood number have been plotted to show the impact of diverse values of the involved flow parameters. The skin friction coefficient is diminished by increasing the curvature and nanoparticles concentration whereas the heat transport rate reduces with the increase of Eckert and Hartmann number. Similarly, the escalating values of Soret number, chemical reaction rate parameter, and the temperature difference parameter enhance mass transportation. Furthermore, the Bejan number decreases with an increase in Brinkman and Hartmann number whereas the fluid's entropy rises for the growing values of thermal radiation and temperature difference parameter.
