Abstract
A method for calculating the permeability of a porous medium is proposed and realized using the example of a rhombohedral porous structure. The method is based on the Darcy equation, while the flow rate is found by numerical simulation of a three-dimensional flow of a viscous incompressible fluid in a pore channel. Computational experiments are performed using open SALOME-OpenFOAM packages. The results of the calculations allow estimating the accuracy of previously obtained analytical estimates of permeability.
