Abstract This article presents the nonlinear, steady state mixed convection boundary layer flow, heat and mass transfer of an incompressible non-Newtonian Jeffrey’s fluid past a non-isothermal wedge. The transformed conservation equations are solved numerically subject to physically appropriate boundary conditions using a versatile, implicit finite-difference Keller box technique. The influence of a number of emerging non-dimensional parameters, namely Deborah number ( De ), ratio of relaxation to retardation times ( λ ), pressure gradient parameter ( m ), Buoyancy ratio parameter ( N ), mixed convection parameter ( λ 1 ) , radiation parameter ( F ) and heat generation/absorption parameter ( Δ ) on velocity, temperature and concentration evolution in the boundary layer regime is examined in detail. Also, the effects of these parameters on surface heat transfer rate , mass transfer rate and local skin friction are investigated.
