CO2 pipeline integrity: A coupled fluid-structure model using a reference equation of state for CO2
Aursand, Eskil; Aursand, Peder; Berstad, Torodd; Dørum, Cato; Hammer, Morten; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Peer reviewed; Journal article, 2013)We present a coupled fluid-structure model to study crack propagation and crack arrest in pipelines. Numerical calculations of crack arrest, crack velocity and pressure profiles have been performed for steel pipes with an ... -
CO2 pipeline integrity: A new evaluation methodology
Berstad, Torodd; Dørum, Cato; Jakobsen, Jana Poplsteinova; Kragset, Steinar; Li, Hailong; Lund, Halvor; Morin, Alexandre; Munkejord, Svend Tollak; Mølnvik, Mona Jacobsen; Nordhagen, Håkon Ottar; Østby, Erling (Peer reviewed; Journal article, 2011)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 ... -
Coupled fluid-solid modelling of the valve dynamics in reciprocating compressors
Ervik, Åsmund; Saai, Afaf; Berstad, Torodd; Meyer, Ole; Tsuji, Takuma; Oku, Tatsuya; Hattori, Kazuhiro; Yamada, Kazuya; Delhaye, Virgile Roger; Nekså, Petter (Science et technique du froid;, Chapter; Peer reviewed, 2022)A novel method coupling computational fluid dynamics (CFD) and finite element method (FEM) was developed to account for the complex physics of the reciprocating compressor. The developed method is based on data exchange ... -
Low-velocity impact behaviour and failure of stiffened steel plates
Gruben, Gaute; Sølvernes, S; Berstad, Torodd; Morin, David; Hopperstad, Odd Sture; Langseth, Magnus (Peer reviewed; Journal article, 2017)The behaviour and failure of stiffened steel plates subjected to transverse loading by an indenter is studied in this paper. Low-velocity dynamic and quasi-static tests of stiffened plates with geometry adopted from a ...
