Abstract: The Brinkman-Forchheime-extended Darcy model and the theory of equilibrium between fluid and porous medium were used to establish the mass conservation equation, momentum conservation equations and energy conservation equation of the two-dimensional laminar flow over an isothermal plate in porous medium. The equations were simplified by analyzing the order of magnitude of each item. The formulas of the velocity distribution and temperature distribution in the boundary layer, and surface viscous friction coefficient, convection heat transfer coefficient have been obtained by use of the integration method. It is shown that the boundary layer thickness in the porous medium increases very quickly at the beginning of the plate and reaches a steady thickness very soon, which is different obviously from that of a plain plate. But the thermal boundary layer thickness increases continuously along the flow direction and is similar to the situation of a plain plate.
