Retention Properties and Permeability of Shales

The water retention mechanisms play a major role in either fluid trapping due to the capillary forces present in low permeability formations, as in the case of shale gas reservoir, or in the resaturation of shale formations after ventilation, as in the cas ...

Contribution of Stern layer and membrane polarization to spectral induced polarization of variably saturated sandy soils

Alessandro Brovelli

Spectral induced polarization is receiving increasing attention as a tool to map subsurface properties in a non-invasive manner. Although empirical correlations have been devised to link measurements to porous medium properties, such as the time constant o ...

HOT TEARING SUSCEPTIBILITY IN DC CAST ALUMINUM ALLOYS

Jean-Marie Drezet, André Phillion

Hot tearing and loss of dimensional stability are two key defects related to industrial aluminum alloy casting processes. In order to investigate their occurrence, a new semi-solid constitutive law [20] for AA5182 that takes into account cooling rate, grai ...

A multiscale Darcy-Brinkman model for fluid flow in fractured porous media

Alfio Quarteroni, Carlo D'Angelo, Matteo Lesinigo

The aim of this work is to present a reduced mathematical model for describing fluid flow in porous media featuring open channels or fractures. The Darcy's law is assumed in the porous domain while the Stokes-Brinkman equations are considered in the fractu ...

Wave-induced watertable fluctuations, sediment transport and beach profile change: Modeling and comparison with large-scale laboratory experiments

David Andrew Barry, Alessandro Brovelli, Roham Bakhtyar

Coastal groundwater systems can have a considerable impact on sediment transport and foreshore evolution in the surf and swash zones. Process-based modeling of wave motion on a permeable beach taking into account wave-aquifer interactions was conducted to ...

Modeling the effectiveness of U(VI) biomineralization in dual porosity porous media

David Andrew Barry

Recent attention has focused on the in situ immobilization of uranium by stimulation of dissimilatory metal-reducing bacteria (DMRB). The objective of this work was to investigate the effectiveness of this approach in heterogeneous and structured porous me ...

Design methodology accounting for the effects of porous medium heterogeneity on hydraulic residence time and biodegradation in horizontal subsurface flow constructed wetlands

David Andrew Barry, Luca Rossi, Alessandro Brovelli, Otoniel Carranza Diaz

Horizontal flow constructed wetlands are engineered systems capable of eliminating a wide range of pollutants from the aquatic environment. Nevertheless, poor hydrodynamic behavior is commonly found resulting in preferential pathways and variations in both ...

Site-Specific CO2 Adsorption and Zero Thermal Expansion in an Anisotropic Pore Network

Wendy Lee Queen

Detailed neutron powder diffraction (NPD) expts. were carried out on the parent and CO2 adsorbed Mg-MOF-74 (MOF: metal-org. framework). Data collected at low temp. revealed two CO2 adsorption sites on the pore surface and multiple changes in the framework ...

Numerical analysis of the Navier-Stokes/Darcy coupling

Alfio Quarteroni, Marco Discacciati

We consider a differential system based on the coupling of the Navier-Stokes and Darcy equations for modeling the interaction between surface and porous media flows. We formulate the problem as an interface equation, we analyze the associated (nonlinear) S ...

Friction factor correlation for CICC's based on a porous media analogy

Luca Bottura

We use an analogy to porous media to derive a correlation for the friction factor in CICC s We start with a review of selected literature work on this topic We then recall the principles of the porous medium analogy and present the main body of our work on ...
