Solar energy is a significant source of clean and renewable energy, which can be harnessed to control global warming/pollution levels. Carreau nanofluid models have been used in the cooling of solar devices so as to upgrade the efficiency of solar energy systems. The energy equation is modeled by adopting nonlinear thermal radiation because it has a major role on the solar energy absorption capacity of nanofluid. Diffusion of species involving chemical reactions in boundary layer flow finds overwhelming applications in pollution studies, polymer production, in the design of chemical processing equipments, and so forth. In view of this, the present article is developed to evaluate the impact of nonlinear thermal radiation, chemical reaction, and applied magnetic field to the flow of Carreau nanoliquid induced by exponentially extendable surface. The outcomes of the preset study include that more magnetized the conducting fluid contributes more controlled motion of both shear thinning and shear thickening fluids. Axial and transverse surface viscous drag forces, rate of heat, and mass transportation augment with raising Weissenberg parameter while temperature and concentration fields attain a descending trend due to it. In addition, augmented temperature ratio parameter upgraded the thermal field.
