Modeling Aspects of Running Ductile Fracture Propagation in High Pressure Line Pipes

Abstract

Multi-physics simulations are becoming increasingly important in the time where full-scale test facilities and materials are turning out costly. Moreover, the new transition trend of energy production from fossil fuels to renewable sources like solar, wind and hydrogen is pushing forward the development of new technologies for harvesting, storage and transportation. For the latter, the existing pipeline network is intended to be utilized for moving a mixture of hydrogen with natural gases from clean hydrogen production centers to consumers. Understanding the coupling of fluid-structure interaction with thermodynamics of the mixtures is imperative to assure more reliable and fail-safe operations of the infrastructure for production and transportation. In this short survey, a phenomenological fracture model along with coupled Eulerian-Lagrangian/Fluid-Structure interaction model is reviewed. It is shown that the obtained simulation results are in good agreement with experimental tests at laboratory scale and full-scale settings.
