D1300 Fluid-structure interaction for hydro-elastic applications - Literature review and recommended methods

This report describes the results obtained in WE 1300 "Fluid-structure interaction for hydro-elastic applications" concerning the literature review on fluid-structure interaction (FSI) and the recommended methods in the frame of EDA project "Next Generation of Propellers (NextProp)", organised under EDA contract No B-1466-GEM1-GP. The main aim of this deliverable is to improve the current understanding of FSI models, able to accurately estimate the performance of flexible composite propeller. In fact, apart from the advantages of composite propellers over their metal counterparts (such as reduced corrosion, low production cost, reduced blade vibrations etc.), deformations of composite propeller blades under loading can alter their hydrodynamic effects and could not be ignored in the hydrodynamic calculations. Therefore, reliable FSI methods able to accurately estimate the performance of flexible propeller are important. The attention is mainly put on two distinct aspects: 1) a literature review concerning the different formulations to be used in the analysis of a coupled FSI problem, and 2) the critical aspects to be considered in the structural modelling of composite propeller for FSI problems.
