Pore Size Distribution in Granular Material Microstructure

Pore Size Distribution in Granular Material Microstructure

Pore scale modeling plays a key role in fluid flow through porous media and associated macroscale constitutive relationships. The polyhedral shape and effective local pore size within granular material microstructure are computed in this study by means of the Euclidean Distance Transform (EDT), a local maxima search (non-maximum suppression), and a segmentation process. Various synthetic packed...

Pore Scale Model of Wet Granular Material

Landslides are one of the main natural threats for both people and infrastructure in mountainousregions. In most cases, landslides are triggered by the loss of cohesion in a soil due to the increasingliquid saturation level after long or intense rainfalls. Only little is known on the triggering of failuresat the microscopic scale due to the limited experimental accessibility and the...

Estimating the Saturated Hydraulic Conductivity of Granular Material, Using Artificial Neural Network, Based on Grain Size Distribution Curve

Porosity and Pore Size Distribution

A soil’s porosity and pore size distribution characterize its pore space, that portion of the soil’s volume that is not occupied by or isolated by solid material. The basic character of the pore space affects and is affected by critical aspects of almost everything that occurs in the soil: the movement of water, air, and other fluids; the transport and the reaction of chemicals; and the residen...

Pore Size Characterization of Vuggy Carbonate Material

Vuggy carbonate material pose significant challenges when it comes to characterization at the pore scale level. The material under study is a highly porous and connected vuggy system with vugs in the millimetre range and permeabilities correspondingly in the tens of Darcy range. Depending on vug accessibility and connectivity, pore size distributions from capillary pressure based methods such a...
