Feedback form is now closed.
The multiphase flow in porous media is important in the research for petroleum reservoirs1. During the processing of oil exploration, the gas, liquid and solid particles may flow through the porous media in the reservoir. A novel solver, named as MPPICmultiphaseInterFoam, was developed using OpenFOAM to simulate multiphase flows in the porous media of a reservoir. This solver is realized by the coupling of DPM (discrete particle modeling) and VOF (volume of fluid) with CFD (computational fluid dynamics) based on MP-PIC (multiphase particle-in-cell) method. After validation, this solver was used to simulate the multiphase flows in oil and gas reservoirs. The Intel Xeon Phi Knights Landing (KNL) processors on an HPC system were employed to carry out the numerical simulations. Optimal performance was realized by parallel programming with MPI and vectorization based on the Intel Xeon Phi KNL processors. It was found that Intel Xeon Phi Knights Landing processors are good to perform the large-scale simulations of multiphase flow in porous media.
