摘要: In this paper we investigate the effects of temperature-dependent viscosity, thermal conductivity and internal heat generation/absorption on MHD flow transfer a non-Newtonian UCM fluid over stretching sheet. The governing partial differential equations are first transformed into coupled non-linear ordinary equation using similarity transformation. resulting intricate boundary value problem is solved numerically by second order finite difference scheme known as Keller-Box method for various values pertinent parameters. Numerical computations performed two different cases namely, zero non-zero viscosity parameter. That is, 1/θr→0 1/θr≠0 to get magnetic field Maxwell parameter velocity temperature fields, several physical situations. Comparisons with previously published works presented special cases. results skin-friction co-efficient Nusselt number changes in tabulated obtained characteristics reveal many interesting behaviors that warrant further study phenomena, especially phenomena. reduces wall-shear stress.
