Modeling of natural gas transportand friction factor for large-scale pipelines: Laboratory experiments and analysis of operational data
Langelandsvik, Leif Idar (Doktoravhandlinger ved NTNU, 1503-8181; 2008:221, Doctoral thesis, 2008)The overall objective of this work was to improve the one-dimensional models used to simulate the transport of single-phase natural gas in Norway’s large-diameter export pipelines. There was a particular focus on the ... -
Modelling and Measuring Transient Flow in Natural Gas Pipelines: Effect of Ambient Heat Transfer Models
Oosterkamp, Antonie (Doctoral thesis at NTNU;2016:163, Doctoral thesis, 2016)The central question of this thesis is how and to what extent the representation of ambient heat transfer in the calculation models contributes to observed deviations between modelled and measured flow parameters in natural ...
