In order to investigate the influence of the vertical variation of porosity on open-channel flow with submerged vegetation, vertical non-homogeneous stumps and stems in submerged vegetation flow are simulated with truncated cones in a laboratory flume. First, porosity is defined as a function of water depth. A new governing equation for vegetation flow is established on the basis of the poroela...

In fractured poroelastic media under high differential stress, the shearing of fractures and faults corresponding propagation wing cracks can be induced by fluid injection. Focusing on low-pressure stimulation with pressures below minimum principal stress but above threshold required to overcome fracture's frictional resistance slip, this paper presents a mathematical model numerical solution a...

BACKGROUND The fluid load support fraction (W(F)/W(T)) can be used to define the mechanical contribution of the interstitial fluid (W(F)) to the total force (W(T)) in the deformation of cartilage. Traditionally, W(F)/W(T) is calculated using complex experimental setups or time-consuming micromechanical poroelastic Finite Element (FE) simulations. AIM To define and validate a fast and efficien...

A refined model is presented which numerically resolves the fluid flow within a fracture inside saturated poroelastic material. At discontinuity, mass balance of solved using velocity profile fracture, with being determined from momentum in integration points at discontinuity. The resolution and discontinuity coupled to surrounding material two-scale approach. resulting monolithic scheme allows...

In this paper, we propose a procedure combining Lattice-Boltzmann and finite element simulations to model the effects of capillary pressure in porous microstructures. Starting from an explicit geometry microstructure, method is used simulate condensation vapor phase liquid predict films phases for arbitrary solid skeleton. Then, provided prescribe surface tension due phases. The skeleton can de...
