Summary:The present paper is devoted to numerical simulation of two-phase two-component isothermal viscous compressible microfows with surface tension and wetting efects within complex voxel-based fow domains. As a basic mathematical model the Navier-Stokes-Cahn- Hilliard (NSCH) equations are utilized. To use easy-to-implement explicit fnite diference approximations we take advantage of regularized (within quasi-hydrodynamic framework) version of NSCH system. The simulation results demonstrate that the developed algorithm for the NSCH system is correct and suitable for solution of industrial level problems thus being a promising technique for simulation of multiphase microfows within complex geometries, including geophysical "digital rock physics" framework.
