This presentation shows the concept of Representative elementary volume known in porous media. The presentation is the results of an excel spreadsheet prepared to generate hypothetical porous media in 2D. It calculates the porosity of the medium at different scales until it reaches the rev value.

1. Representative Elementary
Volume (REV) in Porous Media
Amro Elfeki, PhD

2. Concept REV
• This video shows the concept of REV in porous
media.

3. Concept REV
• It shows generation of porous media of
specified porosity (example n =.5).

4. Concept REV
• For each generated porous media the prosity
is calculated for a number of cells within the
porous media.

5. Concept REV
• A convergence curve is made to show at what
level the REV can be defined.
