Physical Aspects of Homogeneous-Heterogeneous Reactions on MHD Williamson Fluid Flow across a Nonlinear Stretching Curved Surface Together with Convective Boundary Conditions

This article is concerned with the fluid mechanics of MHD steady 2D flow of Williamson fluid over a nonlinear stretching curved surface in conjunction with homogeneous-heterogeneous reactions with convective boundary conditions. An effective similarity transformation is considered that switches the nonlinear partial differential equations riveted to ordinary differential equations. The governing nonlinear coupled differential equations are solved by using MATLAB bvp4c code. The physical features of nondimensional Williamson fluid parameter lambda, power-law stretching index m, curvature parameter K, Schmidt number Sc, magnetic field parameter M, Prandtl number Pr, homogeneous reaction strength k(1), heterogeneous reaction strength k(2), and Biot number gamma are presented through the graphs. The tabulated form of results is obtained for the skin friction coefficient. It is noted that both the homogeneous and heterogeneous reaction strengths reduced the concentration profile.

Automated summary

This article examines the MHD steady 2D flow of Williamson fluid over a nonlinear stretching curved surface, considering homogeneous-heterogeneous reactions. The governing nonlinear coupled differential equations are solved using MATLAB bvp4c code, and the physical features of various parameters are presented through graphs. Both homogeneous and heterogeneous reaction strengths are found to decrease the concentration profile.
