| Popis: |
A coupled fluid-structure model for pipeline integrity simulations has been developed. The pipe material and fracture propagation have been modelled using the finite-element method with a local fracture criterion. The finite-volume method has been employed for the fluid flow inside the pipe. Choked-flow theory was used for calculating the flow through the pipe crack. A comparison to full-scale tests of running ductile fracture in steel pipelines pressurized with hydrogen and with methane has been done, and very promising results have been obtained. It is suggested that the current method may be useful in the design and operation of safe and cost-effective CO2 transport systems. © 2011 Published by Elsevier Ltd.
