Coupling Finite Elements for Modelling Fluid Flow in Fractured Porous Media
(2020-01-01)
The presence of discontinuities such as cracks and faults in porous media can remarkably impact the fluid pressure distribution. This is due to considerable contrast between hydraulic properties of porous matrix and ...
Consolidation of elastic-plastic saturated porous media by the boundary element method
(ELSEVIER SCIENCE SA, 2008)
This paper presents a domain boundary element formulation for inelastic saturated porous media with rate-independent behavior for the solid skeleton. The formulation is then applied to elastic-plastic behavior for the ...
Effect of bio-functional MAO layers on the electrochemical behaviour of highly porous Ti
(2020-03-25)
Ti foams are attractive for orthopaedic applications due to reduced Young's modulus and ability of bone in-growth. However, poor corrosion behaviour and lack of bioactivity are yet to be overcome. In the present work, ...
Modeling the hydrodynamic behavior of fractures and barriers in porous media using coupling finite elements
(2022-01-01)
Fractures, vugs and barriers are geological structures that strongly affect the fluid flow in porous media. While the first two lead to the formation of preferential flow paths, the latter blocks the flow and induces ...
Transverse and longitudinal fluid flow modelling in fractured porous media with non-matching meshes
(2021-01-01)
A new discrete fracture model is introduced to simulate the steady-state fluid flow in discontinuous porous media. The formulation uses a multi-layered approach to capture the effect of both longitudinal and transverse ...
Alumina porous ceramics: mathematical behavior at different commercial starch concentration
(Trans Tech Publications Ltd, 2008-01-01)
Several researches have been developed in order to verify the porosity effect over the ceramic material properties. The starch consolidation casting (SCC) allows to obtain porous ceramics by using starch as a binder and ...
Stability and finite element approximation of phase change models for natural convection in porous media
(2019-11)
In this paper we study a phase change problem for non-isothermal incompressible viscous flows. The underlying continuum is modelled as a viscous Newtonian fluid where the change of phase is either encoded in the viscosity ...
