Numerical modelling of moisture ingress in cracked concrete
(Master thesis, 2017)Concrete is a construction material which service life can be significantly reduced with the presence of cracks when concrete is exposed to aggressive agents such as chlorides. The current service life models for concrete ... -
Numerical modelling of pipeline scour under the combined action of waves and current with free-surface capturing
(Journal article; Peer reviewed, 2019)Understanding the pipeline scour processes under the combined action of waves and current is essential for adequate scour protection measures. This paper presents the numerical modelling of pipeline scour under the ... -
Numerical modelling of residual stress redistribution induced by TIG-dressing
(Peer reviewed; Journal article, 2019)TIG-dressing is a technique used to improve the fatigue strength of welded joints by a remelting of the weld toe region that promotes both a smoother transition between the plate and the weld crown and a residual stress ... -
Numerical modelling of run-out of sensitive clay slide debris
(Master thesis, 2013)Flow slides in sensitive clay deposits are common phenomena in Scandinavia and Canada. These flow slides have caused catastrophes to infrastructure and human life. The post-failure movements of such flow slides usually are ... -
Numerical Modelling of Sailing Hydrofoil Boats
(Master thesis, 2019)Motivasjonen til denne avhandlingen kommer fra ønsket om å lage en treningssimulator for erfarne seilere som ikke er kjent med hydrofoilfartøy. Siden en simulator kan være basert på flere typer numeriske metoder, blir en ... -
Numerical Modelling of Scour Around an Offshore Jacket Structure Using REEF3D
(Lecture Notes in Civil Engineering;LNCE, volume 22, Chapter, 2019)In the present paper, a numerical investigation of the scouring around offshore jacket structure is carried out. The open-source CFD model REEF3D is used for the numerical modelling. The model solves the Reynolds-averaged ... -
Numerical Modelling of Sediment Flow in Tala Desilting Chamber
(Master thesis, 2005)This thesis is about estimation of trap efficiency of desilting basin using numerical model program named as SSIIM. SSIIM is acronym for Sediment Simulation in Intakes with Multiblock Option. It is developed by Dr. Nils ... -
Numerical Modelling of Sediment Transport in the Arctic
(Master thesis, 2015)The purpose of this research is to model coastal erosion mainly dune or bluff erosion in the Arctic for storm event using numerical analysis. A case study of Varandey, Russia is considered for the analysis. The numerical ... -
Numerical Modelling of Separation Efficiency of Sediments in a Combined Sewer Overflow (CSO)
(Master thesis, 2012)Combined sewer overflows (CSOs) are a part of the combined storm water and foul sewer system. CSOs should protect the downstream sewer system against overloading during heavy rainfall and snow melting. This report investigates ... -
Numerical modelling of the effect of waterflooding and surfactant injection in a matrix-fracture system
(Master thesis, 2015)Naturally fractured reservoirs in carbonate rocks usually contain more residual oil in the matrix than other reservoirs, due to the high permeability fracture zones that carries the flooded fluids, leaving parts of the ... -
Numerical modelling of the effects of crystallographic texture and grain structure on the macroscopic behaviour of metals
(Master thesis, 2010)The crystal plasticity theory derives the response of a crystalline material from its structure and the structural defects. This work tries to find this connection. The first part revises the main concepts of the plasticity ... -
Numerical Modelling of the Hydrodynamic Effects of Marine Operations in Broken Ice
(Doctoral thesis at NTNU;2015:281, Doctoral thesis, 2015)For sustainable offshore field development and safe navigation in the Arctic seas, reliable numerical models that are capable of simulating the interactions between structures, water and sea ice are needed. The Discrete ... -
Numerical modelling of the interaction between a fish net and fluid using CFD
(Chapter, 2019)A numerical model for the determination of the deformed shape of nets under consideration of hydrodynamic loads and elastic twines is presented. The hydrodynamic forces are incorporated using Morison's formula and force ... -
Numerical Modelling Of The Interaction Of Moving Fish Nets And Fluid
(Chapter, 2020)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 ... -
