With effective thermal performances and stability, the nanomaterials are intended to be the focus of investigators due to applications in energy systems, thermal extrusions, pharmaceutical processes, diagnoses and therapies, domestic refrigerators, bio-medical technologies, nuclear processes, antibacterial activities, etc. This research addresses thermal transport in stagnation point flow of nanofluid over a curved surface with nonlinear radiative effects and chemical reaction effects. Basic mass and momentum conservation laws are used to model the flow problem, whereas Cattaneo-Christov theories are used in thermal diffusion relations to model the heat and concentration equations. The similarity variables transformed the governing partial differential equations and the resulting equations are numerically simulated by the fourth-order finite difference scheme. The effective change in velocity, heat transfer rate, and mass fluctuation are reported due to effective values of parameters. It is noted that velocity, temperature, and concentration are affected by the curvature of the surface.
