Effect of convective heating on the chemically reactive Williamson fluid flow over a stretching cylinder with Arrhenius activation energy and thermal radiation

The study of flow through the boundary layer for Williamson fluid across a stretchable cylinder can be useful in plastic production, processing of food, medicine delivery systems, and refrigeration technologies. In the flow, we studied the effect of thermal and solutal effects, variable viscosity, natural convection, inclined magnetic fields, thermal radiation, activation energy, source and sink of heat, and Joule heat production. These parameters are important for addressing issues in renewable energy networks, the combustion process, thermal management, and nuclear power stations. In order to address its application in the domains of chemical processing, biomedical engineering, aerodynamics, and environmental applications, we took into account the impact of chemical mechanisms and Soret-Dufour effects on the mass transfer investigation for the current flow. Similarity transformation is used to transform partial differential equations into ordinary differential equations. The well-known bvp4c technique is used for the numerical solution of a set of nonlinear differential equations. This research shows that the changes in the curvature parameter, Williamson fluid parameter, and inclination magnetic field control the Williamson flow characteristics. On the other hand, the temperature dispersion can be improved by adding the Eckert number, Dufour number, and magnetic field. The reaction coefficient indicates a lowering influence on the concentration distribution, while the Soret number and activation energy increase the concentration profile.
