ABSTRAKT

In this paper, the series method is exploited to solve the problem of nonlinear convection in porous a plate with Forchheimer-Boussinesq approximations. The conservation equations that govern the problem are transformed into an infinite number of nonlinear ordinary differential equations in terms of perturbation function. These coupled nonlinear equations are solved numerically using the fourth-order Runge-Kutta method and Newton-Raphson technique. The numerical results of the physical parameters are presented in x-y plots. The validity of our series solution is verified with the heat transfer results of Cheng and Chang [Int. J. Heat Mass Transfer, vol. 19, pp. 1267-1272, 1976] for Darcy flow.
