Modeling of Transient Two Dimensional Flow in Saturated-Unsaturated Porous Media

Numerical Model for Saturated-Unsaturated Flow in Deformable Porous Media

An integrated finite difference algorithm is presented for numerically solving the governing equation of saturated-unsaturated flow in deformable porous media. In recognition that stability of the explicit equation is a local phenomenon a mixed explicit-implicit procedure is used for marching in the time domain. In this scheme the explicit changes in potential are first computed for all element...

Compositional Two-Phase Flow in Saturated-Unsaturated Porous Media: Benchmarks for Phase Appearance/Disappearance

Résumé. The two test cases presented herein aimed at simulating the transport migration of nuclides around a nuclear waste repository and belong to the "Two-Phases Numerical Test Data Base" presented in [1], [2]. They were initially designed in the framework of the French research group MoMaS [3]. The starting point in designing all the test cases presented in [1] comes from some of the main ch...

Three-dimensional microscale flow simulation and colloid transport modeling in saturated soil porous media

Transport of sub-micron colloid particles in soil porous media has been mostly studied numerically with unit-cell-based grain-scale geometries. In this study, we develop a more general approach by combining a multiple-grain pore-scale flow simulation with Lagrangian tracking of individual colloids. First, two numerical methods are applied simultaneously to solve viscous flows in a channel parti...
