Optimal homotopy asymptotic method solution to convection heat transfer flow

Abstract

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.
