Preferential flow through soil macropores in tile drained soils can significantly increase the risk of pollution of surface water bodies by agricultural chemicals such as pesticides. While many field studies have shown the importance of preferential flow in tile-drained fields, few have included detailed numerical modelling of the processes involved. The objective of this study was to compare f...

In industry, the porosity of petrochemical reservoirs is measured frequently by coring and is an important property when trying to determine if a site is appropriate for drilling. Porosity can also be used in waste water treatment in order to determine if a material is ideal for water purification in industrial or residential applications. The purpose of this experiment was to simulate a oil re...

Anomalous velocity and porosity are often indicators of abnormal pore pressure. It is important, therefore, to be able to link velocity to porosity and rock texture in a rational, firstprinciple-based manner. The critical porosity concept allows for building such rock physics models. Critical porosity is the porosity above which the rock can exist only as a suspension. In sandstones the critica...

In this paper, we report an analysis of pressed paper in terms of porosity and permeability. Previously, we reported a pressed paper that exhibits decreased porosity and permeability. Additionally, its applications into programmed sample delivery as well as flow rate control were reported. However, there is a need for a theoretical analysis of pressed paper in terms of porosity and permeability...

La caractŽrisation et la simulation dynamique des rŽservoirs naturellement fracturŽs ont bŽnŽficiŽ d'avancŽes importantes ces dernires annŽes. Toutefois, l'ingŽnieur rŽservoir reste confrontŽ ˆ la difficultŽ de paramŽtrer le modle Žquivalent ˆ double porositŽ utilisŽ pour reprŽsenter de tels rŽservoirs. En particulier, les permŽabilitŽs de fracture Žquivalentes et les dimensions du bloc matri...

The objective of the present work is to demonstrate the effect of pore structure on fluid transport and electrical properties of homogeneous or dual-porosity pore structures for drainage conditions. To this end, a pore network numerical simulator is used that calculates multiphase flow and electrical properties taking into account the pore structure specificities. The characteristics of the 3-D...

The effect of porosity on the elastic behavior of cast steel is investigated experimentally, and an approach for including porosity effects in finite element analysis (FEA) simulations is presented. Porous cast steel specimens are mechanically tested having apparent elastic moduli reduced between 17 and 61 pct. Analysis of radiographs and tomography is used to measure and reconstruct the porosi...
