Investigation on Numerical Simulation of VIV of Deep-Sea Flexible Risers
نویسندگان
چکیده
The vortex-induced vibration (VIV) of flexible risers is a complex fluid–structure interaction (FSI) phenomenon. In this study, we conducted numerical simulation method based on the slicing to study deep-sea with different slenderness ratios and uniform flow velocities. combines finite element model riser structure two-dimensional field slices solved by Fluent solver. was realized self-compiled UDF program overset mesh technique. results were validated comparing them experimental data. VIV characteristics riser, such as track, mode, frequency wake vortex shedding analyzed. article reveals nonlinear dynamic features vibration, multi-frequency wide-frequency multi-modal vibration. also provides insights into mechanism risers.

Monitoring VIV fatigue damage on marine risers
Long flexible cylinders (e.g. risers, tendons, mooring lines) exposed to the marine environment encounter ocean currents leading to vortex-induced vibration (VIV). These oscillations, often driven at high frequencies over extended periods of time may result in structural failure of the member due to fatigue damage accumulation. Recent developments in instrumentation and installation of data acq...
متن کاملVIV of Tapered Cylinders: 3D LES Numerical Simulation
In the present study, the author’s previous experimental investigations on the vortex induced vibration of uniform and tapered circular cylinders are numerically simulated. The circular cylinders have medium mass ratios (5.93, 6.1), low mass-damping parameters (0.0275, 0.0279) a mean diameter of 0.028m and an aspect ratio of about 14. A fully coupled two-way fluid-structure interaction (FSI) an...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
