Written by an eminent authority in the field, Modelling of Mechanical Systems: Fluid-Structure Interaction is the third in a series of four self-contained volumes suitable for practitioners, academics and students alike in engineering, physical sciences and applied mechanics. The series skilfully weaves a theoretical and pragmatic approach to modelling mechanical systems and to analysing the responses of these systems. The study of fluid-structure interactions in this third volume covers the coupled dynamics of solids and fluids, restricted to the case of oscillatory motions about a state of static equilibrium. Physical and mathematical aspects of modelling these mechanisms are described in depth and illustrated by numerous worked out exercises.

Von der hinteren Coverseite

The study of fluid-structure interactions in this third volume covers the coupled dynamics of solids and fluids, restricted to the case of oscillatory motions about a state of static equilibrium. Fluid motion induced by a vibrating structure results from various distinct coupling mechanisms operating together but with a relative importance which varies enormously from one case to the other. Physical and mathematical aspects of modelling these mechanisms are described in depth and illustrated by numerous worked out exercises. As in Volumes 1 and 2, whilst focusing on linear problems, a few nonlinear problems are also included. Chapter 1 gives a preview to the subject. Chapter 2 deals with the inertial coupling which can modify profoundly the in vacuo natural frequencies and mode shapes of the structure. Chapter 3 describes the surface waves at a liquid-gas interface, focusing on gravity waves, sloshing modes and their coupling to vibrating structures. Chapter 4 is devoted to plane acoustical waves in piping and duct networks. The subject is extended in Chapter 5 to the cases of 2D and 3D sound waves in waveguides and large enclosures. The vibroacoustic coupling mechanism is analysed in Chapter 6, which addresses in particular the numerical methods of interest for engineering applications. Finally, Chapter 7 presents various dissipative effects including radiation damping and dissipation due to the viscosity of the fluid. The subject serves, in particular, as a preliminary to the non conservative fluid-structure interaction mechanisms encountered in flow-induced vibration problems which will make the subject of Volume 4 of this series.
