CFD Simulations of Vortex-Induced Vibrations of a Subsea Pipeline Near a Horizontal Plane Wall
Janocha, Marek Jan (Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018-06)Subsea pipelines, when exposed to free spans, can experience vortex-induced vibrations. This phenomenon was described as a resonance condition occurring when the vortex shedding frequency and the natural frequency of a ... -
Computational Fluid Dynamics (CFD) Investigations of Flow-Induced Vibrations of Two Rigidly Coupled Cylinders at High Reynolds Number
Pires Vieira Serta, Clarissa (Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020)Two degree-of-freedom (2-DoF) flow-induced vibrations (FIV) of a single cylinder and two rigidly coupled cylinders are numerically investigated at the Reynolds number of 3.6 × 10^6. Two-dimensional (2D) Unsteady ... -
Dynamic and Fatigue Analyses of Suspended Power Cables for Multiple Floating Offshore Wind Turbines
Beier, Dennis (Master thesis, 2023)Floating offshore wind turbines (FOWTs) are installed to effectively capture energy from offshore wind in deeper water areas where building bottom-fixed offshore wind turbines is not practical. The present study focuses ... -
Numerical Simulations of Near-Wall Vortex-Induced Vibrations of two Circular Cylinders in Tandem
Eie, Kjartan (Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-15)Free-spanning subsea pipelines may experience vortex-induced vibrations (VIV) when exposed to fluid flow. These resonant motions can cause fatigue-related problems and in some cases failure of the pipe. A common configuration ... -
Three-dimensional Numerical Simulations and Proper Orthogonal Decomposition Analysis of Flow Around a Flexibly Supported Circular Cylinder
Fabricius, Lukas Philip (Master thesis, 2021)Numerical simulations of turbulent flow around stationary and vibrating cylinders at Re = 3900 are performed using the Large Eddy Simulation (LES) approach. Detailed convergence and validation studies confirm feasibility ...
