DEVELOPMENT OF A CFD-BASED SCREENING TOOL FOR VIV PREDICTION
Résumé
This paper presents an efficient screening tool, based on the 2D strip method, which allows the study of the dynamics of the vortex-induced vibration (VIV) phenomenon with almost the same accuracy of a fully 3D Fluid-Structure interaction (FSI) CFD-based approach, but with a reduction in computational times by a factor of nearly 20 compared to the 3D approach. Such a large reduction makes the use of CFD-based analysis feasible on a workstation within a reasonable time frame and opens the possibility of CFD approaches in a subsea pipeline design process.
