This book is the collection of 11 chapters that have been contributed by each research unit joining a MIUR (Italian Ministry of University and Research) project, devoted to the topic of fluid structure interaction. The subject matter is divided into chapters covering a wide spectrum of recognized areas of research, such as: wall bounded turbulence; quasi 2-D turbulence; canopy turbulence; large eddy simulation; lake hydrodynamics; hydraulic hysteresis; liquid impacts; flow-induced vibrations; sloshing flows; transient pipe flow; and air entrainment in dropshaft. The purpose of each chapter is to summarize the main results obtained by the individual research unit. As a.
