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...
