Gas generation may occur in a deep underground repository of radioactive waste. This gas may be released through the engineered barrier and flow through the geological barrier. The Evegas benchmark project aims at the verification and the validation of numerical software for modelling two phase flow phenomena (water/gas) in low permeability porous media.

The project is organized in three phases:

- Phase 1: Analysis of the codes and treatment of a simple problem with analytical solution;
- Phase 2: Calculation of a few problems based on laboratory experiments;
- Phase 3: Modelling of a repository scenario.

Final reports on phase 1 and phase 3 have already been published under EUR 16639 EN and EUR 16557 EN respectively.

In this report the phase 2 problems are described which involve the simulation of a gas injection experiment at laboratory at constant flow rate and at a constant temperature in a vertical plug made up of eight samples. All required experimental data were supplied. It appeared that all codes gave satisfactory results compared to the experimental data. tal data.
