Abstract: The momentum transport phenomena at the interface of porous media and fluid are numerically investigated. The single domain approach is used with matching boundary conditions; i.e., the Brinkman-Forchheimer-extended Darcy equation is used for the present study. Five typical porous media found in natural and engineered systems are selected in order to cover a wide range of the Darcy number (6.25x10-4 ≥ Da ≥ 5.90x10-11. In addition, six different Reynolds numbers (10 ≥ Re ≥ 1000) are tested for each case. The importance of viscous shear stress at the interface into the porous medium, a transition region of disturbed flow in the porous medium, and the depth of penetration are discussed.
