“MODELING ISSUES FOR SUBSEA GAS TRANSPORT PIPELINES”
Prof. Ytrehus
Professor Emeritus Tor Ytrehus
Department of Energy and Process Technology
Norwegian University of Science and Technology
The seminar will focus on fluid mechanics issues for subsea transport of gas in long export pipelines, with specific reference to the GASSCO1)-operated infrastructure between the coast of Norway and continental Europe and UK. Turbulent pipe-flow at high Reynolds numbers of the order of 107, and with pressure differences from 300 –to 20bar will be considered for pipelines of length up to 1000km. Computed results will be compared to “real life” situations for steady and transient flow events. Some attention to basic fluid mechanics elements, like details of the dissipation function in turbulent pipe flow, and consistent use of classical correlations for heat transfer, will be given along with some remarks on state equations for real gases.
