Numerical Solution og Coupled CFD Problems by the Domain Decomposition Method
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:102, Doctoral thesis, 2004)In this thesis we look at the efficient numerical solution of two complex multi-physics problems which both have very important applications. The first problem is related to the numerical simulation of extrusion of aluminium. ... -
Numerical solutions of stochastic partial differential equations
(Doktoravhandlinger ved NTNU, 1503-8181; 89, Doctoral thesis, 2002)The main part of this thesis is devoted to the analysis of stochastic partial differential equations of Wick-type. In particular, we study numerical approximations of solutions to boundary value problems for such equations. The ... -

Numerical Solutions of Traffic Flow on Networks: Using the LWR-Model and the Godunov Scheme
(Master thesis, 2014)This paper shows how to create a simulationtool for traffic flow in a network using the Lighthill--Witham--Richards model and the Godunov scheme. First some basic rules about conservation laws are described and how to solve ... -
A numerical solver for coupled dynamic simulation of glacial ice impacts considering hydrodynamic-ice-structure interaction
(Peer reviewed; Journal article, 2021)Glacial ice features pose great threats on the safety of ships and offshore structures in the arctic. House sized bergy bits or growlers are of particular concern because of the detection capability limits of marine radars. ... -
Numerical Solvers for Transient Two-Phase Flow
(Doctoral Theses at NTNU, 1503-8181; 2013:202, Doctoral thesis, 2013)Certain numerical methods have been well developed for solving one-dimensional two-phase flow (e.g. gas and liquid) problems in the literatures during the last two decades. Based on the existing methods, the present work ... -
Numerical studies of mitral valve regurgitation
(Master thesis, 2011)Mitral regurgitation (MR) has been studied through the use of computational fluid dynamics (CFD).The ambition of the work is to improve understanding of mitral regurgitation fluid dynamics in order to improve quantification ... -
Numerical studies of particle clustering in circular cylinder wake flows
(Doctoral theses at NTNU;2022:51, Doctoral thesis, 2022)The emphasis of this thesis is to investigate how inertial point particles are clustered and dispersed in the wake of a circular cylinder with an uniform free stream. The numerical simulations that directly solved Navier-Stokes ... -
Numerical studies of Supernova Remnants
(Master thesis, 2013)Supernovae are very luminous events, on the scale of entire galaxies, and deposit mass and large amounts of energy in to the surrounding interstellar medium. In this workthe effect of a supernova on the surrounding medium ... -
Numerical studies of the scattering of light from a two-dimensional randomly rough interface between two dielectric media
(Journal article; Peer reviewed, 2016)The scattering of polarized light incident from one dielectric medium on its two-dimensional randomly rough interface with a second dielectric medium is studied. A reduced Rayleigh equation for the scattering amplitudes ... -
Numerical studies of the transmission of light through a two-dimensional randomly rough interface
(Journal article; Peer reviewed, 2017)The transmission of polarized light through a two-dimensional randomly rough interface between two dielectric media has been much less studied, by any approach, than the reflection of light from such an interface. We have ... -
Numerical studies of viscous flow around bluff bodies
(Doctoral thesis at NTNU;2015:94, Doctoral thesis, 2015)A bluff body, i.e. an object with blunt rather than streamlined shape, exposed to external flow gives rise to a multitude of flow patterns depending on the timeand length-scales, the free-stream velocity, and the viscosity ... -
Numerical Studies of Viscous Flow Around Step Cylinders
(Doctoral theses at NTNU;2021:122, Doctoral thesis, 2021)A step cylinder consists of a small diameter cylinder (d) attached coaxially to a large diameter cylinder (D). Structures with a similar shape as the step cylinder have been extensively used in many marine engineering ap- ... -
Numerical studies of viscous flow around straight and curved tandem cylinders
(Doctoral theses at NTNU;2024:81, Doctoral thesis, 2024)The physics of flow around straight and curved cylinders in tandem is investigated by means of direct numerical simulations (DNS), for transitional and turbulent flow regimes. For straight tandem cylinders in the reattachment ... -
Numerical studies on ductile failure of aluminium alloys
(Doctoral theses at NTNU;2017:284, Doctoral thesis, 2017)Numerical modelling and simulation are becoming increasingly important for structural design and assessment, and they are essential tools for engineers facing the challenges and demands imposed by the modern society. Using ... -
Numerical studies on the dynamic behavior of a superlong curved pontoon bridge under wind and wave actions
(Chapter, 2019)Floating bridges serve as attractive solutions where classical bridge concepts are not possible. However, compared to more commonly encountered bridge concepts such as cablesupported bridges, their dynamic behavior remains ... -
Numerical studies on wave forces and moored ship motions in intermediate and shallow water
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:238, Doctoral thesis, 2012)Wave forces and motions of a moored ship in intermediate and shallow water depth are investigated numerically in the present thesis. The studies are carried out in the framework of potential flow theory. Three numerical ... -
Numerical Study for a Catamaran Gripper-Monopile Mechanism of a Novel Offshore Wind Turbine Assembly Installation Procedure
(Chapter; Peer reviewed, 2017)Current methods for installation of offshore wind turbines are all sensitive to the weather conditions and the present cost level of offshore wind power is more than twice the cost of land-based units, increasing with water ... -
Numerical Study for Single Blade Installation of an Offshore Wind Turbine
(Master thesis, 2020)Markedet for havvind vokser samtidig som størrelsen på vindmøllene øker. Effektiviteten til en vindturbin påvirkes av turbinstørrelsen og stabile vindforhold. En følge av dette vil være flere installasjoner av vindmøller ... -
