Study and modeling of head losses in GH2 pipelines
Goals
Determining pressure losses (total pressure losses) in pipelines. Evolution with operating time (in terms of years/decades of use) due to degradation of the pipe's internal surface condition caused by H2 attack (hydrogen embrittlement) under pressure and erosion.
Innovations
- Couple numerical methods for fluid calculation with structural code for pipe walls (effects of friction, erosion, radial pressure gradient, etc.) with GH2.
- Wall erosion issues - Definition of Finnie-type erosion model
- Validate models and numerical results obtained with test results: Scottish Gas Network project H100 Fife 2020, UK National Gas project HyNTS Futuregrid, tests with BeBlue).
