Data for "Saturation hysteresis during cyclic injections of immiscible fluids in porous media: an invasion percolation study"

The data contains the algorithms for generating the data of fluid-fluid displacement processes in porous media.ModifiedInvasionPercolation_cyclic.rar: the modified invasion percolation algorithm for simulating cyclic immiscible displacement processes. Trapping is by default enabled. The run-time pore filling pressure is updated according to the pore coupling coefficient.Run demo_1stInjection.m and then demo_2ndInjection.m for a demonstration. More cycles can be simulated by alternately calling these two functions.ITA_multiphase-main.rar: This interface tracking algorithm (ITA) simulates immiscible fluid-fluid displacement processes in two-dimensional porous media in the quasi-static (capillary-dominated) regime under different wetting conditions (controlled by the contact angle).Run "main_demo.m" for a demonstration.For more details, please refer to the manuscript "Saturation hysteresis during cyclic injections of immiscible fluids in porous media: an invasion percolation study".The pore-resolved interface tracking algorithm is also available at https://github.com/spoonacular/ITA_multiphase.
