Second Order Slip Flow of Cu-Water Nanofluid Over a Stretching Sheet With Heat Transfer

The boundary layer flow of Cu-water based nanofluid with heat transfer over a stretching sheet is numerically studied. Second order velocity slip flow model is considered instead of no-slip at the boundary. The governing partial differential equations are transformed into ordinary one using similarity transformation, before being solved numerically. Numerical solutions of these equations are obtained using finite element method (FEM). The variations of the velocity and temperature distribution as well as the skin friction and the heat transfer coefficients for some values of the governing parameters, namely, the nanoparticle volume fraction and slip parameters are shown graphically and discussed. Comparison with published results for pure fluid flow case is presented and it is found to be in excellent agreement.
