Fluid-Structure-Interaction-Analysis concerning Damping Features of Viscous Fluids

Authors


Abstract

This work deals with Fluid-Structure-Interaction (FSI) concerning damping characteristics of viscous liquids, which are investigated to make the offshore structures more secure and efficient. On that account, we modeled a damping element prototype consisting essentially of an elastic cover that is attached to the cylindrical mono pile foundation at the height of waves. Within the framework of FSI, the impact of breaking waves on a three-dimensional model of a damping element prototype corresponding to [1] is simulated. In order to measure the influence of different liquid properties on the damping of the impact, the calculations are set up using newtonian and non-newtonian fluids with varying viscosity. For the non-newtonian investigation verification is carried out with a CFD model. (© 2012 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim)
