Hydrodynamic interaction among vertical axisymmetric bodies restrained in waves

摘要: This paper deals with the linearised hydrodynamic interaction problem of regular, small amplitude, surface gravity waves and a stationary group large, vertical axisymmetric bodies. The developed numerical procedure is based on physical idea multiple scattering in conjunction appropriate eigenfunction expansions for velocity potential fluid domain around each body configuration. By superposing incident harmonic wave various orders scattering, due to remaining bodies, vicinity particular obtained. method presented applicable an arbitrary number bodies revolution having any geometrical arrangement individual geometries. Numerical results concerning exciting forces moments configurations, commonly used offshore applications, are compared those other authors pertinent experimental data.
