  3. Abstract:
  4. The aim of this work is to investigate flow hydrodynamics in porous media. Random non-overlapping spherical particles in a cylindrical geometry were produced as a porous media. Navier-Stokes equations in three-dimensional porous packed bed have been solved and dimensionless pressure drop has been studied for a fluid flow through the porous media at different Reynolds numbers (based on pore permeability and interstitial fluid velocity). The numerical results are in good agreement with those reported by Macdonald (1979) in the range of Reynolds numbers studied. At higher Reynolds numbers turbulent models such as large eddy simulation (LES) and Reynolds stress model (RSM) also have been employed for modeling turbulence flows through irregular array of particles. The results obtained show that LES compare to RSM can predict the fluid flow better in high Reynolds numbers. Also it is found that in turbulent regime, laminar model can predict the flow dynamics as well as LES, and it is clear that working with laminar model is easier than turbulent models
