 Overview

 We aim to bring together experimental observation and numerical modeling of multiphase flow and transport, as well as evolution processes such as solid phase alteration via precipitation/dissolution on the pore (grain) length scale. We define the pore scale as the length scale where void and solid spaces are distinct and resolved to their relevant size, as opposed to being averaged. Visualization is an integral part of both experiments and simulation and ultimately needed for understanding of any physical process. Porous systems, however, are notorious for their complexity, and comprehension of the processes taking place is nontrivial.

Focus in 2011-12: Visualization (and Image Analysis)

 The data produced, either by various imaging modalities (such as X-ray tomography, magnetic resonance imaging, or confocal microscopy) or by numerical simulators is ever increasing in size. To exemplify, a typical volumetric data set nowadays contains 1024³ points (about 2GB of memory), while 2048³ is common in X-ray microtomography. Thus, merely reading in the entire data into memory can take time, and displaying or extracting some useful quantity requires advanced numerical techniques. While some rather powerful software for the visualization and analysis of volumetric data has recently emerged both free of charge (Paraview/VTK and ITK, VisIt, Drishti, ImageVis3D) and commercially (Avizo), the use of such software is not part of the standard hydrology or engineering curriculum. This focus group will try to mend this gap by organizing graduate student workshops during 2011-12 and making the materials permanently available on the InterPore website.

 

Proposed activities for 2011-12

 Interpore Focus Group on Pore Scale Modeling and Visualization is pleased to announce
"Short Course and Workshop on Image Analysis for Porous Media"

Time: July 12-14, 2011 (Short Course); July 14-15, 2011 (Workshop)

Short course application required, deadline: May 1, 2011 (limited to 40 participants)
Workshop open to all, registration starts April 15, 2011

Place: University of Texas at Austin, Texas, USA

Imaging of porous materials, as well as the changes due to various
processes such as flow within their voids or exposure to external
stress, is becoming a ubiquitous method of material characterization as
well as simulation validation. We are organizing two events with this
important focus:
- The short course will provide graduate students and researchers with
basic training in image analysis for porous media.
- The workshop will present an overview of the latest advances in image
analysis, characterization and related modeling of porous media.
