In the present study, we have perceived the impact of nonlinear thermal radiation on heat transfer analysis of Carreau nanofluid flow through wedge by considering slip conditions into account. The extremely nonlinear partial differential equations are transformed into nonlinear ordinary differential equations by using suitable similarity variables, and these equations together with boundary conditions are solved by using the most extensively validated finite element method. The impact of various pertinent parameters, such as Weissenberg number, wedge angle parameter, radiation parameter, temperature ratio parameter, Prandtl number, thermophoresis parameter, Brownian motion parameter, constant velocity ratio parameter, suction parameter, temperature slip parameter, Lewis number, power law index parameter, concentration slip parameter, chemical reaction parameter and magnetic parameter, on velocity, temperature and concentration profiles is calculated and is revealed through graphs. The values of Nusselt number, Sherwood number and skin friction coefficient are also calculated and shown in tables. It is noticed that there is a remarkable intensification in the values of Nusselt number, Sherwood number and skin friction coefficient as the values of Weissenberg number rise. The temperature and concentration distributions both intensify with rising values of temperature slip parameter ( ξ ).
