Physical and numerical large-scale wave basin modeling of fluid-structure interaction and wave impact phenomena

Abstract

Physical and numerical large-scale wave basin (LSWB) modeling of fluid-structure interaction (FSI) and wave impact phenomena are examined in this study. In particular, the role of numerical modeling and simulation in designand analysis of physical LSWB FSI andwave impact experiments using a numerical wave basin (NWB) modeling approach is examined. Physical characteristics and testing capabilities of arepresentative LSWBare first described. Selectedphysical FSI and wave impactexperiments pertaining to civil, energy and naval engineering disciplines conducted at the LSWB and the accompanying NWBFSI modeling and simulations of these challenging phenomenaare presented. An effort to further improvetheNWBFSI softwarewith highly nonlinear wave impact modeling capabilities to facilitate physical FSI experiment design and testing,and details of an on-goingNWBdevelopment and validation processesare delineated.It is demonstrated that the NWBFSI software is useful in facilitating the design of complex, highly nonlinear FSI and wave impactexperiments. Conversely, the resulting measured data from the FSI and wave impact experiments can be used to validate and identify further modeling improvement needs of the NWBFSI and wave impactsoftware.
