Numerical simulations of flow-induced vibrations of two rigidly coupled cylinders with uneven diameters in the upper transition Reynolds number regime
Pires Vieira Serta, Clarissa; Janocha, Marek Jan; Yin, Guang; Ong, Muk Chen (Peer reviewed; Journal article, 2021)Two degree-of-freedom (2-DoF) flow-induced vibrations (FIV) of two rigidly coupled cylinders are numerically investigated at the Reynolds number of 3.6 × 106. Two- dimensional (2D) Unsteady Reynolds-Averaged Navier–Stokes ... -
Numerical simulations of gas-liquid two-phase flow induced forces on 90-degere elbow structures
Zeng, Weixin (Master thesis, 2023)90-degree elbow structures such as pipelines with bends and rigid jumpers, are commonly used for flow transportation in subsea systems. The produced flow from the subsea wells is normally a multiphase flow which is a mixture ... -
Numerical Study of Oxygen Transport in Aquaculture Tanks With Different Geometries
Pollen, Trygve (Master thesis, 2022)The transport of dissolved oxygen concentration in water for aquaculture is a core parameter affecting the quality of yielded fish. An emerging shift from offshore to land-based aquaculture presents advan- tages to marine ... -
On the three-dimensional effects of the water entry of wedges
Wen, Xueliang; Ong, Muk Chen; Yin, Guang (Peer reviewed; Journal article, 2023-09)Three-dimensional (3D) effects on the total and spanwise slamming coefficients and the pressure reductions acting on the wedge surface during water entry are modeled in a unified manner. First, the water entry of wedges ... -
On the wake flow behind a sphere in a pipe flow at low Reynolds numbers
Yin, Guang; Ong, Muk Chen (Peer reviewed; Journal article, 2020-10)Numerical simulations are carried out to investigate the flow around a stationary sphere in a pipe. Seven sphere diameters d = 0.1D–0.9D (D is the diameter of the pipe) are chosen to investigate the effects of the blockage ... -
Reduced Order Models for Hydrodynamic Analysis of Pipelines based on Modal Analysis and Machine Learning
Nazvanova, Anastasiia (Master thesis, 2023)Bluff bodies have extensive implementation in engineering. For instance, marine risers, jumpers, umbilicals, and bundle flowlines are the examples of the circular bluff bodies which are used in the field of offshore ... -
Three-dimensional Large Eddy Simulations and Proper Orthogonal Decomposition Analysis of Flow around a Flexibly Supported Circular Cylinder
Janocha, Marek Jan; Fabricius, Lukas Philip; Yin, Guang; Ong, Muk Chen (Peer reviewed; Journal article, 2022)Three-dimensional (3D) numerical simulations of the flow around a cylinder undergoing vortex-induced vibration (VIV) at Re = 3900 (defined as Re = U infinity D/nu, where U-infinity is the inlet flow velocity, D is the ... -
Three-dimensional numerical simulations and proper orthogonal decomposition analysis of flow over different bottom-mounted ribs
Serta Fraga, Vinicius; Yin, Guang; Ong, Muk Chen (Peer reviewed; Journal article, 2021)Turbulent flow over bottom-mounted ribs is investigated using three-dimensional (3D) Spalart-Allmaras Delayed Detached-Eddy Simulations (SADDES). The ribs are subjected to a boundary layer flow with a thickness of δ/H=0.73 ... -
Validation and assessment of different RANS turbulence models for simulating turbulent flow through an orifice plate
Jurga, Agata Patrycja; Janocha, Marek Jan; Yin, Guang; Giljarhus, Knut Erik Teigen; Ong, Muk Chen (Peer reviewed; Journal article, 2021)In the present study, numerical simulations using different Reynolds-Averaged Navier–Stokes (RANS) turbulence models are carried out to investigate the turbulent flow through the orifice plate at Reynolds number (Re) of ...
