Numerical modeling of breaking wave induced seawall scour
(Journal article; Peer reviewed, 2019)cour is recognised as one of the major causes of seawall failure. This paper presents numerical modelling of seawall scour due to wave impact on a vertical seawall. The modelling of waves hydrodynamics is based on the ... -
Numerical Modeling of Combined Hydraulics and Infiltration in Grassed Swales
(Master thesis, 2014)The aim of this thesis is to establish a numerical model capable of simulating combined infiltration and hydraulic discharge through grassed swales. The model is intended for making assessments of the hydraulics within ... -
Numerical Modeling of Cyclic Loading on Clay
(Master thesis, 2014)Soil`s behavior, when subjected to cyclic loading, may often be reduced stiffness giving large deformations. For undrained conditions a possible pore pressure build-up will reduce the capacity even further. This may affect ... -
Numerical Modeling of Effective Thermal Conductivity of Hollow Silica Nanosphere Packings
(Peer reviewed; Journal article, 2021)Hollow silica nanosphere packings (HSNSPs) can significantly suppress heat conduction through solid and gas phases due to the voids, small interparticle contact areas, and nanosized pores, showing promising potentials ... -
Numerical Modeling of Flow Over Trapezoidal Broad-Crested Weir
(Journal article; Peer reviewed, 2011)Two computational fluid dynamics (CFD) codes, Flow-3D and SSIIM 2, have been used to calculate the water flow over a trapezoidal broad-crested weir. The two programs apply different algorithms for making the grid and ... -
Numerical Modeling of Power Take-Off Damping in an Oscillating Water Column Device
(Journal article; Peer reviewed, 2015)An Oscillating Water Column (OWC) is a wave energy converter consisting of a partially submerged chamber with an air column over the water column. The work done by the air column under excitation by the incident waves is ... -
Numerical Modeling of Swelling Rock
(Master thesis, 2010)This master thesis is focusing on numerical modeling of a swelling rock called anhydrite. If water gets in contact with the rock anhydrite (CaSO4) it transforms into gypsum (CaSO4•2H2O). This chemical process can result ... -
Numerical Modeling of the Effects of Toe Configuration on Throughflow in Rockfill Dams
(Peer reviewed; Journal article, 2021)The rockfill toe structure situated within the downstream slope of rockfill dams is an integral part of a defense mechanism safeguarding the dam structure in throughflow situations. Recent studies have concluded that the ... -
Numerical Modeling of the Interaction of Moving Fish Nets and Fluid
(Peer reviewed; Journal article, 2022)The significant difference in length scales between the flow around a moving fish net and the flow around each twine of the net prevents the resolution of the complete structure within a discrete fluid domain. In this ... -
Numerical Modeling of Wave Hydrodynamics and Wave Interaction with Porous Structures with REEF3D
(Master thesis, 2016)In order to validate the wave hydrodynamics calculated in REEF3D, experiments will be carried out at the wave flume. The experiments will involve studying wave propagation and wave kinematics through the measurement of ... -
Numerical modeling to estimate the impact of built infrastructure on permafrost degradation - Case study from Ilulissat, Greenland
(Master thesis, 2023)Infrastruktur i permafrostlandskap påvirker bakkens termiske regime og kan øke permafrostens nedbrytning. Stabiliteten og brukbarheten til infrastrukturen avhenger likeledes av de termiske forholdene i undergrunnen. ... -
Numerical Modelling and Experiments on Sea Spray Icing
(Doctoral thesis at NTNU;2014:338, Doctoral thesis, 2014)Oil and gas activities in the cold seas are endangered by icing. Icing may occur when water spray or moisture is deposited on a vessel or offshore structure above sea level and the air temperatures is below the freezing ... -
