Hydrodynamic Modeling of Porous Media/Experimental Model of Water Filter

A study conducted to examine several selected water filter's Medias such as crushed silica, crushed anthracite coal, glass beads crushed porcilinaite and crushed garnet. a large spread of particle size(0.5mm-2mm), porosity (35%-60%)   and physical temperature(20^oC-80^oC) were tested in order to validate the experimental modeling of both Darcy’s and Forchheimer’s law parameters

  Typical constants of  head loss in porous media as function to velocity using Forchheimer^,s model ( _{dh/dl= a v + b v ²} ) has been correlated  by using hydraulic conductivity coefficients a*,b* which are experimentally evaluated at based conditions (T_w=25^oC) ,(n=50%),(d=1mm). Empirical equations for different  selected porous media and filter's characteristics  could be approximate to use  Forchheimer^,s model            Keywords :porous media ,Forchheimer regime , water filter, pressure loss head
