The objective of this research is to develop advanced CFD capabilities for improving the prediction of riser VIV responses at high Reynolds number. The performance of VIV suppression devices such as helical strakes and fairings is also evaluated. This report documents the following tasks accomplished under this project:
- Development of advanced CFD capabilities: numerical method and parallelization
- 2-D simulations of flow past a fixed riser at high Reynolds numbers
- Surface roughness effects
- 2-D simulations of elastically mounted risers undergoing VIV at high Reynolds number: single isolated riser and arrangements of multiple risers
- 3-D Large Eddy Simulation of flow past a fixed riser
- 3-D Large Eddy Simulation of an elastically mounted riser undergoing VIV
- Simulations of an elastically mounted riser outfitted with a fairing
- Simulations of an elastically mounted riser with helical strakes
