Simulation of breaking focused waves over a slope with a CFD based numerical wave tank
(Chapter, 2017)Extreme wave conditions are always identified with large-amplitude breaking waves in shallow waters. Focused waves can often be used to describe extreme waves which evolve during the nonlinear wave-wave interaction, occurring ... -
Simulation of Chemical Reactors using the Least-Squares Spectral Element method
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:308, Doctoral thesis, 2011)The least–squares spectral element method is a relatively novel method that can be used to solve any well–posed problem. It has been extensively used in computational fluid dynamics, and in recent years has been applied ... -
Simulation of Clay Swelling Behavior and Mass Transport Utilizing a Discrete Element Method
(Master thesis, 2021)Denne masteroppgaven har som hovedmål å lage en enkel modell for å utforske svelling av leirepartikler i skifer. Modellens oppførsel og numeriske resultater vil også sammenlignes med eksperimentelt arbeid utført på nettopp ... -
Simulation of CO2 Injection in a Reservoir with an Underlying Paleo Residual Oil Zone
(Master thesis, 2018)Paleo residual oil zones (PROZs) are zones below the oil-water contact (OWC) that contain residual oil. These types of zones exist in many fields around the world, but is often given little attention, due to traditionally ... -
Simulation of Combined Hydrate Control and H2S Removal Using Aspen Plus
(Master thesis, 2016)Removal of water (H2O) and acid gas contaminants, like hydrogen sulfide (H2S) and carbon dioxide (CO2), are essential in natural gas purification. Due to gas quality specifications and protection of installed equipment ... -
Simulation of counterparty risk in the Norwegian financial market
(Master thesis, 2006)This work will study different methods to estimate counterparty credit risk, where the methods represent both analytical approximation and simulation based method. The somewhat more analytical approximation that will be ... -
Simulation of crack propagation using isogeometric analysis applied with NURBS and LR B-splines
(Master thesis, 2012)This report features the isogeometric finite element method applied to the elastodynamic problem in a brittle medium with a potential for cracking. Griffith's theory for fracturing is used. The development of the model is ... -
Simulation of drilling riser disconnection - Recoil analysis
(Master thesis, 2013)The emergency disconnection system and recoil analysis is required for every offshore drilling unit. Situations can occur where the vessel needs to disconnect from the well, it can be to large forces that are being transferred ... -
Simulation of dual mixed refrigerant natural gas liquefaction processes using a nonsmooth framework
(Journal article; Peer reviewed, 2018)Natural gas liquefaction is an energy intensive process where the feed is cooled from ambient temperature down to cryogenic temperatures. Different liquefaction cycles exist depending on the application, with dual mixed ... -
Simulation of ductile crack propagation in dual-phase steel
(Journal article; Peer reviewed, 2013)The modified Mohr–Coulomb and the extended Cockcroft–Latham fracture criteria are used in explicit finite-element (FE) simulations of ductile crack propagation in a dual-phase steel sheet. The sheet is discretized using ... -
Simulation of Ductile Crack Propagation in Steel Pipes
(Master thesis, 2018)For the transport of gases and liquids, such as CO2, in steel pipelines to be safe, rupture in the pipe should be avoided. A crack in a pressurized pipe may start to propagate rapidly along the pipeline and run for ... -
Simulation of ductile fracture in aluminium alloys with random or strong texture using heuristic extensions of the Gurson model
(Peer reviewed; Journal article, 2022)Ductile fracture of two high-strength aluminium alloys in temper T6 is investigated using heuristic extensions of the Gurson model with non-quadratic yield criteria. Simulations of tensile tests on smooth and notched ... -
Simulation of ductile-to-brittle transition combining complete Gurson model and CZM with application to hydrogen embrittlement
(Journal article; Peer reviewed, 2022)A general simulation framework for modelling ductile-to-brittle transition in metals is proposed. The method combines the complete Gurson model and cohesive zone model, which brings ductile and brittle fracture mechanisms ... -
