Multiscale modeling of wave propagation on the Norwegian Coast
Madrigal Sanchez, Alonso (Master thesis, 2018)Fjords coastlines are attributed to glaciers as the main agent of erosion. Thus, fjords are characterised by an irregular coastline configuration and rapid changes in their deep and steep slopes. These features generate a ... -
Numerical investigation on scour around a cylinder and stabilities of scour protections
Jorde, Lars Ottar (Master thesis, 2022)En tredimensjonal numerisk modell brukes til å undersøke lokal erosjon rundt en sylinder i en rektangulær kanal under strøm. Numerisk modellering av erosjon rundt en sylinder er utfordrende fordi beregningene krever at man ... -
Numerical Investigation on Wave-Overtopping at a Double-Dike Defence Structure in Response to Climate Change-Induced Sea Level Rise
Jin, Yueyuan; Wang, Weizhi; Kamath, Arun; Bihs, Hans (Journal article; Peer reviewed, 2022) -
Numerical Modelling of Wave Overtopping Response to Sea Level Rise with REEF3D::SFLOW
Jin, Yueyuan (Master thesis, 2020)Klimaendringer har vært et hovedtema på forskningsområdet nylig fordi det påvirker menneskets livsmiljø. I kystsonen og lavtliggende området forårsaker klimaendringer havnivåstigning, noe som medfører potensiell fare for ... -
Reduction of the wave propagation error of a sigma grid based numerical tank using a vertical spacing based on the constant truncation error
Pakozdi, Csaba; Wang, Weizhi; Kamath, Arun; Bihs, Hans (Peer reviewed; Journal article, 2021)Numerical wave models that solve the Laplace equation for the velocity potential with a -grid in the vertical direction have been proven to be flexible and efficient. However, it is observed that the dispersion relation ... -
REEF3D::FNPF – A Flexible Fully Nonlinear Potential Flow Solver
Bihs, Hans; Wang, Weizhi; Pakozdi, Csaba; Kamath, Arun (Peer reviewed; Journal article, 2020)In situations where the calculation of ocean wave propagation and impact on structures are required, fast numerical solvers are desired in order to find relevant wave events. Computational fluid dynamics (CFD)-based numerical ... -
Representation of 3-h Offshore Short-Crested Wave Field in the Fully Nonlinear Potential Flow Model REEF3D::FNPF
Wang, Weizhi; Pakozdi, Csaba; Kamath, Arun; Bihs, Hans (Peer reviewed; Journal article, 2022)Stochastic wave properties are crucial for the design of offshore structures. Short-crested seas are commonly seen at the sites of offshore structures, especially during storm events. A long time duration is required in ... -
Representation of Breaking Wave Kinematics in the Fully Nonlinear Potential Flow Model REEF3D::FNPF
Pakozdi, Csaba; Kamath, Arun; Wang, Weizhi; Bihs, Hans (Chapter, 2020)Robust simulations over three-hours are essential to represent a stationary sea state and derive wave statistics and structural response of marine structures in a reliable manner. This means that the numerical model used ... -
Submerged Floating Tunnel: Water-Structure Interaction
Popov, Daniil (Master thesis, 2019)Denne studien fokuserer på interaksjonen mellom vann og et nedsenket flytende rør i homogene og lagdelte strømmer, samt utvikling av formet av tyngdekraften. Det siste ble gjort for å sette opp og validere numerisk modell ... -
Validation of Numerical Wave Tank Simulations Using REEF3D With JONSWAP Spectra in Intermediate Water Depth
Pakozdi, Csaba; Fouques, Sebastien; Thys, Maxime; Kamath, Arun Mulky; Wang, Weizhi; Hoseini Dadmarzi, Fatemeh; Bachynski, Erin Elizabeth; Bihs, Hans Sebastian (;Paper No: OMAE2020-18298, V001T01A012, Chapter, 2020)As offshore wind turbines increase in size and output, the support structures are also growing. More sophisticated assessment of the hydrodynamic loads is needed, particularly for the ultimate limit state design. For ... -
Wave environment assessment at a Norwegian harbor for land-based aquaculture facilities using a combined numerical approach
Reidulff, Knut (Master thesis, 2021)Numerical wave modeling of Norwegian coastal areas is challenging due to the strongly varying bathymetry, irregular coastline, and large domains of interest. Phase-averaged models provide an appealing solution due to their ...
