摘要: 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 conditions using versatile, implicit finite-difference Keller box technique. influence number emerging non-dimensional parameters, namely Deborah ( De ), ratio relaxation retardation times λ pressure gradient parameter m Buoyancy N 1 ) , radiation F generation/absorption Δ on velocity, temperature concentration evolution in regime is examined detail. Also, effects these parameters surface rate local skin friction investigated.
