Binary chemical reaction, Soret and Dufour effects on Williamson nanofluid flow over a stretching cylindrical porous sheet

The intention of the paper is to scrutinize the combined impacts of binary chemical reaction, Soret and Dufour effects on Magnetohydrodynamics (MHD) Williamson nanofluid flow over a steady stretching cylindrical porous sheet. Similarity transformation and linearization technique are used to transform the governing non-linear partial differential equations into a system of first order initial value problems. The Runge–Kutta fourth order with the shooting technique aided with python programming is used to solve the system of initial value problems. The implemented method is validated with formerly published article. Graphs are used to observe the influence of different parameters on velocity, temperature and concentration profiles. Moreover, in response to different parameters, the effects of skin friction, heat and mass flux dynamics are presented. The results of the study revealed that the temperature near the cylinder’s wall is initiated whereas the concentration gets retarded as the respective Soret and Dufour numbers are increased. The coefficient of skin friction rises and hence the velocity is declined for higher values of Forchheimer number. As Soret, Dufour numbers and destructive chemical reaction parameter are increased, the rate of heat flux is retarded.
