CFD Investigation on Hydrodynamic Resistance of a Novel Subsea Shuttle Tanker
Xing, Yihan; Janocha, Marek Jan; Yin, Guang; Ong, Muk Chen (Peer reviewed; Journal article, 2021-12)The Subsea Shuttle Tanker (SST) was proposed by Equinor as an alternative to subsea pipelines and surface tankers for the transportation of liquid carbon dioxide (CO2) from existing offshore/land facilities to marginal ... -
Estimation of Hydrodynamic Forces on Cylinders Undergoing Flow-Induced Vibrations Based on Modal Analysis
Yin, Guang; Janocha, Marek Jan; Ong, Muk Chen (Peer reviewed; Journal article, 2022)The objective of the present study is estimating hydrodynamic forces acting on cylinders undergoing vortex-induced vibration (VIV) using dynamic mode decomposition (DMD). The cylinders are subjected to a uniform incoming ... -
Flow around two elastically-mounted cylinders with different diameters in tandem and staggered configurations in the subcritical Reynolds number regime
Janocha, Marek Jan; Ong, Muk Chen; Nystrøm, Per Richard; Tu, Zhenguo; Endal, Geir; Stokholm, Halvor (Peer reviewed; Journal article, 2021)Flow around two cylinders with different diameters undergoing Flow-Induced Vibrations (FIV) in the subcritical flow regime is investigated using two-dimensional Unsteady Reynolds Averaged Navier-Stokes (URANS) approach. ... -
Large eddy simulations of flow past an inclined circular cylinder: Insights into the three-dimensional effect
Li, Gen; Li, Wenhua; Janocha, Marek Jan; Yin, Guang; Ong, Muk Chen (Peer reviewed; Journal article, 2023)The flow past an inclined cylinder is simulated using large eddy simulations to study the three-dimensional wake flow effects on the forces on the cylinder at Re = 3900. Four inclination angles of α = 0°, 30°, 45°, and 60° ... -
Numerical simulation of piggyback pipelaying under current loadings
Lee, Chern Fong; Ji, Guomin; Janocha, Marek Jan; Ong, Muk Chen; Borsheim, Andreas (Peer reviewed; Journal article, 2023)For piggyback pipelaying operations, current-induced force and its effect on the piggyback pipe have not been thoroughly studied. In the present study, an improved method in hydrodynamic load calculation and structural ... -
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 ... -
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 ... -
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 ...
