The phase averge Navier-Stokes equation presents the foundation for the present quantification of high Reynolds number crossflow through prismatic porous media. A representative unit cell (RUC) model, based on a microstructure typification of the porous media, is discussed. A new interpretation of the model leads to an improvement in the closed form quantification of the pore scale fluid-solid interaction in the Darcy-Forchheimer transitional flow region, as well as the full Forchheimer flow region. The presented unified flow model renders the phase average Navier-Stokes equation a powerful tool for numerical analysis of transport of momentum transverse to prismatic porous media, over the whole laminar flow region. Validity of the model interpretation is demonstrated through comparison with numerical flow solutions at the pore scale, as well as experimental results for flow across heat transfer tube banks.
