Multifysikk simulering av fysiske prosesser med ulike tidskonstanter
(Master thesis, 2019)Reservoarsimuleringer kan være kostbare og tidkrevende da et typisk reservoar kan være i størrelsesorden av hundrevis av millioner kubikkmeter og produsere i flere tiår. I et forsøk på å redusere simuleringstiden samtidig ... -
Multiphase flow simulation of rich gas pipelines with traces of liquid glycol - Flerfasesimulering av rikgassrørledninger med små mengder glykol væske
(Master thesis, 2016)Long distance transport of multiphase flow is an important technology in the development of oil and gas fields. Predicting phase behaviour in long pipelines is a demanding and complicated process. To realistically simulate ... -
Multiphase Flow with Gas Hydrate Particles
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:49, Doctoral thesis, 2013)“Cold Flow Technology” (CFT) is an alternative solution to deal with gas hydrate formation in subsea flowlines. Transient multiphase flow with gas hydrate particles is an important research area of the CFT, which has not ... -
Multiple Holdup Solutions and the Effect of Interface Level Gradients
(Master thesis, 2012)Simulations on liquid loads and flow rates which the Taitel-Dukler model predicts to have multiple solutions have been performed with ANSYS Fluent and LedaFlow. Both steady state and transient results in one, two and three ... -
