A Stokes Permeability Solver for Three-Dimensional Porous Media



Dale P. Bentz, Nicos Martys


A set of C and Fortran computer programs have been developed for computing the permeability of three-dimensional porous media under incompressible Stokes flow conditions. In this NISTIR, the background for developing these codes is reviewed and the detailed code listings are also presented in an appendix. The codes are also available for free downloading from the NIST anonymous ftp site at While currently being employed to simulate the permeability of model pervious concretes, the codes have been utilized in the past on a wide variety of model and real (computer tomography) three-dimensional microstructures.
