In this paper, we apply optimal homotopy asymptotic method (OHAM) to compute an approximation to solve the problem of forced convection over a horizontal flat plate. We investigate in this work, that OHAM, being independent of free parameter, provides greater accuracy and yields a good agreement. Moreover, its convergence domain can be easily adjusted and controlled, which shows that OHAM is more effective and easy than the other approximate method.


Key words: Convection heat transfer, optimal homotopy asymptotic method (OHAM), nonlinear equation, convergence constant h.
