摘要

Numerical solutions are presented for a laminar steady three-dimensional boundary-layer flow of non-Newtonian fluid over a convective stretching surface in the presence of nanoparticles. The effects of an internal heat generation/absorption, thermal radiation, Brownian motion, and thermophoresis are also taken into account. The viscoelastic fluid model is employed to describe the non-Newtonian fluid. The governing partial differential equations are reduced to a set of four coupled nonlinear ordinary differential equations using suitable similarity transformations. The resultant equations are solved numerically by employing the well-known Runge-Kutta-Fehlberg method with the shooting technique. The effect of pertinent parameters on skin friction coefficient in the x and y directions, local Nusswelt number, local Sherwood number, velocity in the x and y directions, temperature, and nanoparticle volume fraction profile are studied and discussed in detail.
