A numerical study on vortex-induced vibrations and the effect of slurry density variations on fatigue of ocean mining risers
(Journal article; Peer reviewed, 2019)Ocean mining emerges as a way of meeting future demands for valuable minerals. Risers conveying ore from the seabed to the surface must withstand large wave and current loads. In addition, vortex-induced vibrations (VIV) ... -
Assessment of algebraic subgrid scale models for the flow over a triangular cylinder at Re = 45000
(Peer reviewed; Journal article, 2021)The turbulent separated flow over an equilateral triangular cylinder at a Reynolds number 45000 (based on the triangle edge) is studied by means of large-eddy simulation (LES). The moderate Reynolds number is chosen in ... -
Large-eddy simulations of the flow past a bluff-body with active flow control based on trapped vortex cells at Re = 50000
(Peer reviewed; Journal article, 2023)We investigate a novel flow control concept, which allows to govern bluff-body wake dynamics and the laminar–turbulent transition by suppressing vortex shedding and obtaining the mostly detached flow. Large-eddy simulations ... -
Maritime Shipping and Emissions: A three-layered, damage based approach
(Journal article; Peer reviewed, 2015-12-01)Policy emphasis in ship design must be shifted away from global and idealized towards regional based and realistic vessel operating conditions. The present approach to reducing shipping emissions through technical standards ... -
A novel method for estimating missing values in ship principal data
(Peer reviewed; Journal article, 2022)Missing values in the fleet data set acquired in the marine sector reduce the data available for analysis, which can decrease the statistical power of the model and negatively affects the energy-efficient operation and ...
