چکیده

Three dimensional flow of non-Newtonian viscoelastic fluid with the variation in the viscosity over a stretching surface is investigated. The governing partial differential equations of continuity, momemtum, energy and concentration are transformed into nonlinear ordinary differential equations by using similarity transformations. The transformed equations are solved numerically by fourth-order Runge-Kutta shooting method. The effects of viscosity, heat and the stretching ratio parameters with Prandtle and Schmidt numbers on the velocity, temperature and concentration distributions have been discussed and illustrated graphically.
