Abstract EN
Cylindrical structures are commonly used in offshore engineering, for example, a tension-leg platform(TLP).
Prediction of hydrodynamic loadings on those cylindrical structures is one of important issues in design of those marine structures.
This study aims to provide a numerical model to simulate fluid-structure interaction around the cylindrical structures and to estimate those loadings using the direct-forcing immersed boundary method.
Oscillatory flows are considered to simulate the flowcaused by progressive waves in shallow water.
Virtual forces due to the existence of those cylindrical structures are distributed in the fluid domain in the established immersed boundary model.
As a results, influence of the marine structure on the fluid flow is included in the model.
Furthermore, hydrodynamic loadings exerted on the marine structure are determined by the integral of virtualforces according to Newton’s third law.
A square array of four cylinders is considered as the marine structure in this study.
Time histories of inline and lift coefficients are provided in the numerical study.
The proposed approach can be useful for scientists and engineers who would like to understand the interaction of the oscillatory flow with the cylinder array or to estimate hydrodynamic loading on the array of cylinders.
