Accurate representations of slip and transitional flow regimes present a challenge in the simulation of rarefied gas flow in confined systems with complex geometries. In these regimes, continuum-based formulations may not capture the physics correctl

The Talbot–Ogden hydrology model provides a fast mass conservative method to compute infiltration in unsaturated soils. As a replacement for a model based on Richards equation, it separates the groundwater movement into infiltration and redistribut

We formulate a coupled vibration problem between a structure and an acoustic field by FEM (finite element methods). The problem leads to a nonstandard eigenvalue problem. Furthermore, we introduce a coupling strength parameter ε as a multiplier appl

A coupled dual porosity Stokes model has been proposed in recent years to help modeling fractured porous media with large conduits. A numerical solution of such a model that works in both 2D and 3D in parallel has been implemented using FEniCS. In th

Coupling of dual porosity flow and free flow arises in many important applications, e.g., groundwater system and industrial filtrations. Existing Stokes-Darcy types of models cannot accurately describe this type of coupled problem since they only con
