Application of Explicit Schemes for the Simulation of the Two-Phase Filtration Process

摘要

In the paper, the new model based on the kinetic approach is proposed to describe the pro- cess of two-phase slightly compressible fluid filtration. The capillary and gravity forces are taken into account. The obtained hyperbolic continuity equations for phase liquids are approximated by the explicit three-level schemes with a sufficiently mild stability condition. Due to its logical simplicity, the computational algorithm can be easily adapted to the hybrid architecture of modern supercomput- ers. The results of computations on a graphics accelerator are presented for the problem on contami- nant infiltration into water-saturated soil and the high parallelization efficiency is demonstrated.
