Simulation of CO2–water two‐phase fluid displacement characteristics based on the phase field method

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 725-738, December 2025.
In the present study, a two‐dimensional numerical model of porous media was developed using the actual pore structure of the core sample. The phase field method was utilized to simulate the impact of the displacement velocity, the water–gas viscosity ratio, and the density ratio on the flow behavior of two‐phase fluids in porous media. Abstract The two‐
