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).
