Stagnation-Point Flow of a Nanofluid Over a Nonlinear Stretching Sheet

Submitted: May 15, 2013; Accepted: Jun 23, 2013; Published: Jul 22, 2013 Abstract: Stagnation-point flow of a nanofluid over a nonlinear stretching sheet is investigated theoretically when the sheet is stretched with a power law velocity under a constant wall temperature. The governing nonlinear problem incorporates the effects of Brownian motion and thermophoresis is transformed by using appropriate similarity transformations into ordinary differential equations. These equations along with boundary conditions are solved numerically by using implicit finite difference scheme known as the Keller-box method. The obtained numerical results are plotted graphically for the interesting flow parameters. The results of Khan and Pop [6] are reduced as the limiting cases of the present studies.
