Numerical modelling of pipeline scour under the combined action of waves and current with free-surface capturing
Ahmad, Nadeem (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 ... -
Three-dimensional numerical modeling of local scour around a non-slender cylinder under varying wave conditions
Ahmad, Nadeem; Afzal, Mohammad Saud; Bihs, Hans; Arntsen, Øivind Asgeir (Chapter, 2015)The three-dimensional numerical model REEF3D is used to simulate the detailed flow field and sediment transport around a non-slender cylinder under regular waves. The location of the free surface is calculated with the ... -
Three-dimensional numerical modelling of wave-induced scour around piles in a side-by-side arrangement
Ahmad, Nadeem; Bihs, Hans; Myrhaug, Dag; Kamath, Arun; Arntsen, Øivind Asgeir (Journal article; Peer reviewed, 2018)The paper presents the numerical modelling of wave-induced scour around piles in a side-by-side arrangement using the open-source CFD model REEF3D. The model solves the Reynolds-Averaged Navier-Stokes equations to calculate ... -
