Application of quasihydrodynamic equation for direct numerical simulation of flow in core samples
Abstract:
The paper is concerned with direct numerical modeling techniques for determination of macroscopic permeability coefficient of samples of naturally occurring geological media using their micro-CT images. Basic mathematical model of flow is based on quasihydrodynamic (QHD) equations of viscous heat-conducting compressible gas flows. Determination of permeability coefficient of artificial and real porous media is discussed. Publicly available micro-CT images are used. Results of computations for artificial porous media are compared with the analytic ones, for real porous media — with the results obtained by Lattice Boltzmann method and results published elsewhere. It is showed that approach based on QHD equations is highly competitive with other approaches.
