摘要：

This work addresses the magnetohydrodynamic (MHD) stagnation point flow of Carreau fluid in presence of heterogeneous-homogeneous reactions. Flow is caused by nonlinearly stretching with variable sheet thickness and convective boundary condition. An electrically conducting fluid is considered in presence of non-uniform applied magnetic field. The governing equations of motion, energy and concentration are transformed into a set of nonlinear ordinary differential equations by utilizing the suitable transformations. Built-in Shooting technique is implemented to obtained the numerical solutions of resulting nonlinear systems. Characteristics of involved parameters on the velocity, temperature and concentration fields are plotted and examined. The skin friction coefficient and heat transfer at the surface are tabulated and analyzed for different physical parameters of interest.
