Development and Applications of the Free-surface Random Vortex Method (FSRVM)


Book Description

"The objective of this work is to apply the free-surface random vortex method (FSRVM) to study the interactions of surface waves and bodies. A FSRVM-based "numerical wavetank" is used to calculate forces on submerged bodies. To study the response of a freely-floating body in waves, the dynamic coupling between a rigid body and the fluid is formulated. To further improve the efficiency of the FSRVM, merger and decay of blobs are introduced to alleviate computational efforts of vortex interactions" [Source : extrait de l'abstract, p. 1].







Twenty-Third Symposium on Naval Hydrodynamics


Book Description

"Vive la Revolution!" was the theme of the Twenty-Third Symposium on Naval Hydrodynamics held in Val de Reuil, France, from September 17-22, 2000 as more than 140 experts in ship design, construction, and operation came together to exchange naval research developments. The forum encouraged both formal and informal discussion of presented papers, and the occasion provides an opportunity for direct communication between international peers. This book includes sixty-three papers presented at the symposium which was organized jointly by the Office of Naval Research, the National Research Council (Naval Studies Board), and the Bassin d'Essais des Carènes. This book includes the ten topical areas discussed at the symposium: wave-induced motions and loads, hydrodynamics in ship design, propulsor hydrodynamics and hydroacoustics, CFD validation, viscous ship hydrodynamics, cavitation and bubbly flow, wave hydrodynamics, wake dynamics, shallow water hydrodynamics, and fluid dynamics in the naval context.






















Smoothed Particle Hydrodynamics


Book Description

This is the first-ever book on smoothed particle hydrodynamics (SPH) and its variations, covering the theoretical background, numerical techniques, code implementation issues, and many novel and interesting applications. It contains many appealing and practical examples, including free surface flows, high explosive detonation and explosion, underwater explosion and water mitigation of explosive shocks, high velocity impact and penetration, and multiple scale simulations coupled with the molecular dynamics method. An SPH source code is provided and coupling of SPH and molecular dynamics is discussed for multiscale simulation, making this a friendly book for readers and SPH users.
