    Abstract

    Direct numerical simulations of the Darcy and non-Darcy flows through plates with circular holes are carried out at the pore scale. With a view to evaluating the linear (or Darcy drag) and non-linear drag (or Forchheimer drag) of perforated plates, the dependence of pressure drop on the transpiration velocity is first discussed for a porosity of 0.1∼0.4 and hole depth to diameter ratio of 1∼6 at pore-level Reynolds numbers of up to 25. The shear flow problems are then investigated, along with a discussion of the effects of the porosity and hole depth to diameter ratio on the slip velocity at the free-fluid/porous medium interface. Correlations of the permeability and Forchheimer coefficient are also proposed for a perforated plate.
