Transport Property Estimation of Non-Uniform Porous Media

In this work a glass micromodel which its grains and pores are non-uniform in size,shape and distribution is considered as porous medium. a two-dimensional random network modelof micromodel with non-uniform pores has been constructed. the non-uniformity of porous model isachieved by assigning parametric distribution functions to pores throat and pores length, which wasmeasured using image analysis technique. statically derived expressions have been used forprediction of macroscopic properties of porous model including: dispersion coefficients,permeability-porosity ratio and capillary pressure. the results confirmed that predicted transportproperties are in good agreement with the available experimental data.
