First Order Approximate Solutions for Nanofluid Boundary Layer Flow past a Stretching Sheet with a Convective Heating Boundary Condition Using OHAM.

Approximate solutions are given to investigate the problem of nanofluid boundary layer flow, heat & mass transfer past a stretching sheet with a convective heating boundary condition. Governing PDEs equations of the problem are converted into nonlinear ODEs via similarity variables and then solved analytically using OHAM. The problem is first modeled and solved by optimal homotopy asymptotic method. This approach does not need any discretization, linearization, small or large parameter in the equations. OHAM results up to first order approximation are found in an excellent agreement with the numerical one obtained by Rung-Kutta Fehleberg method. [ABSTRACT FROM AUTHOR]
