Poroelasticity equations describe the interaction between fluid flow and solids deformation within a porous medium. Modeling of poroelasticity is coupling between elastic deformation of porous materials and Darcy’s law. Poroelasticity has numerous real world applications such as in reservoir engineering, bio-engineering, environmental engineering etc. We have used quasi-static poroelastic ...

This analysis evaluates the importance of the lateral component of flow on the infiltration of water from parallel strip sources of water on the soil surface. Flow from such sources will be two-dimensional, having both vertical and lateral components. Here we examine the effect of the spacing between parallel strip sources and the texture of the soil on the rate of infiltration through a given ...

Nowadays, gas and nuclear waste storage, shale gas and EOR exploitation rise the need to understand and predict the fate of multiphase flows in the underground. Various formulations for multiphase flow arise from different linear combinations of governing equations and choice of associated unknowns. Each formulation has its own benefits and drawbacks; and the optimal may vary depending on the ...

In The Netherlands rising dampness problems due to flooding of rivers and high groundwater levels form an essential treat for monumental buildings and heritage. A number of cases exists where rising dampness problems lead to the deterioration of wall finishes but also of valuable wall paintings in churches and castles. To explore the problem and to look for solutions like drying regimes, ...

Electric, magnetic and electromagnetic (em) methods are widely used to monitor active volcanoes. A review of such applications is presented in Johnston (cit). Em signals were recorded in correspondence of numerous volcanic eruptions, for example in the case of the Mt. Unzen in Giapppone, of Merapi in Indonesia, Etna in Italy and during rapid deformation in Long Valley in California. ...

A similarity solution to Taylor's paint scraper problem for the flow of a non-Newtonian power-law fluid is presented. A shooting method numerical solution agrees with the results found for Newtonian fluids and is able to capture both shear-thinning and shear-thickening fluids. Simulations created in COMSOL Multiphysics® software are also presented to corroborate the shooting method and display ...

Radionuclide sorption is often simulated using a lumped approach where retention processes are represented by the distribution coefficient (Kd), which relates the radionuclide mass retained in the solid phase to its aqueous concentration. Classical Kd-based simulations rely on two strong assumptions: Kd depends on soil properties and is constant in time. However, sorption processes depend also ...

The Levant has been repeatedly devastated by numerous earthquakes since prehistorical times. In order to understand the role of the dynamics of the water bodies in triggering the deformations in the Levant basin, a new theoretical thermo-mechanical model is constructed and extended by including a fluid flow component, in COMSOL Multiphysics simulation environment. The latter is modeled on a ...

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of the bricks, in particular the predicted time at which brick shrinkage reverses into expansion, generating large ...

The groundwater flow is accompanied by the electric field with potential called usually the streaming potential or the Self-Potential (SP) to be measured on the ground surface (e.g., Rizzo et al., 2004; Bolève et al., 2007; Jardani et al., 2009). We studied numerically the SP signals associated with pumping test experiments in layered aquifers using COMSOL Multiphysics® software and GWFGEM ...
