Fluid-Structure Interaction (eBook, ePUB)

Numerical Simulation Techniques for Naval Applications

• Format: ePub

Produktbeschreibung

This book provides a comprehensive overview of the numerical simulation of fluid-structure interaction (FSI) for application in marine engineering. Fluid-Structure Interaction details a wide range of modeling methods (numerical, semi-analytical, empirical), calculation methods (finite element, boundary element, finite volume, lattice Boltzmann method) and numerical approaches (reduced order models and coupling strategy, among others). Written by a group of experts and researchers from the naval sector, this book is intended for those involved in research or design who are looking to gain an overall picture of hydrodynamics, seakeeping and performance under extreme loads, noise and vibration. Using a concise, didactic approach, the book describes the ways in which numerical simulation contributes to modeling and understanding fluid-structure interaction for designing and optimizing the ships of the future.
