An Experimental and Numerical Study of Added Mass and Damping for Side by Side Plates in Oscillating Flow
Solaas, Frøydis; Mentzoni, Fredrik; Abrahamsen-Prsic, Mia; Kristiansen, Trygve (Chapter, 2019)Forced harmonic oscillations of seven configurations consisting of horizontal side by side plate elements are performed experimentally and numerically. The configurations are oscillated in vertical direction and represent ... -
Hydrodynamic Coefficients of Simplified Subsea Structures
Mentzoni, Fredrik; Abrahamsen-Prsic, Mia; Kristiansen, Trygve (Chapter, 2018)Simplified two-dimensional models, representing components of complex subsea structures, are experimentally investigated. Individual as well as combinations of components in different configurations are tested, in order ... -
Large Eddy Simulations of flow around a circular cylinder close to a flat seabed
Abrahamsen-Prsic, Mia; Ong, Muk Chen; Pettersen, Bjørnar; Myrhaug, Dag (Journal article, 2016)Large Eddy Simulations (LES) with Smagorinsky subgrid scale model are used to study the turbulent flow and wake dynamics behind a circular cylinder close to a horizontal, plane wall at subcritical Reynolds number. The focus ... -
Large Eddy Simulations of Flow around a Circular Cylinder in the Vicinity of a Wall at Reynold Number of 13100
Abrahamsen-Prsic, Mia; Ong, Muk Chen; Pettersen, Bjørnar; Myrhaug, Dag (Chapter, 2013)The flow around a circular cylinder in the vicinity of a rigid wall at Reynolds number 13100 is simulated using Large Eddy Simulations (LES) with Smagorinsky subgrid scale model. The main purpose of the present work is to ... -
Large Eddy Simulations of flow around a smooth circular cylinder in a uniform current in the subcritical flow regime
Abrahamsen-Prsic, Mia; Ong, Muk Chen; Pettersen, Bjørnar; Myrhaug, Dag (Journal article; Peer reviewed, 2014)Three-dimensional flow around a circular cylinder in a steady, uniform current at subcritical Reynolds numbers (Re) is investigated.
