In this communication, the dynamics of a non‐Newtonian tangent hyperbolic fluid with nanoparticles past a nonuniformly thickened stretching surface is discussed. We examine the impact of nonlinear mixed convection flow of a hyperbolic tangent fluid with the Cattaneo‐Christov heat and mass diffusion model past a bidirectional stretching surface. The effects of activation energy and magnetic field are incorporated in the analysis. The variables of transformations are used to change the nonlinear partial differential equations into ordinary differential equations (ODEs). Then, these ODEs are numerically solved using the Matlab routine of the bvp4c algorithm. The derailed analysis of the influences of the governing parameters on velocities along the x ‐ and y ‐axes, temperature and concentration profiles are presented using tables and figures. The outcomes of these parameters reveal that the velocities along the x ‐ and y ‐axes are decreased for the values of We increasing but the opposite behavior is observed as the value of A increases. The results also show that the values of e and N b rise as the temperature profiles increase. Similar influences are observed on the profile of concentration as the values of F and f rise. As the values of N 1 go from 0.27 to 0.25, the skin‐friction coefficient increases, and similarly, as N b goes from 0.3 to 0.1, − θ ′ ( 0 )is enhanced.
