This book provides a comprehensive description of the latest
theory-supported numerical technologies, as well as scientific and
engineering applications for water surface waves. Its contents are
crafted to cater to a step-by-step learning of computational wave
dynamics and ocean wave modeling. It provides a comprehensive
description from underlying theories of free-surface flows, to
practical computational applications for coastal and ocean
engineering on the basis of computational fluid dynamics (CFD).The
text may be used as a textbook for advanced undergraduate students
and graduate students to understand the theoretical background of
wave computations, and the recent progress of computational
techniques for free-surface and interfacial flows, such as Volume
of Fluid (VOF), Constrained Interpolation Profile (CIP), Lagrangian
Particle (SPH, MPS), Distinct Element (DEM) and Euler-Lagrange
Hybrid Methods.It is also suitable for researchers and engineers
who wish to apply CFD techniques to ocean modeling and practical
coastal problems involving sediment transport, wave-structure
interaction and surf zone flows.
Dynamics of Water Surface Flows and Waves provides theoretical
descriptions of the whole life of water surface waves through their
birth, propagation, evolution and finally breaking. While initial
capillary waves are created via instability at air-water
interfaces, potential wave theories adequately describe
interactions of waves with current, bathymetry and structure. In
the final breaking stage, potential fluid motions in the waves
rapidly evolve into vortical turbulent flows that disturb the
surfaces, resulting in entrainment of air-bubbles and ejection of
sea spray in bursting bubbles floating on the surface. All theories
and analytical methods required to understand the series of wave
processes, over diverse areas of subjects, including turbulence,
diffusion, vortex and capillary dynamics, shallow water approach,
and stability analysis, as well as the conventional potential wave
theory, are comprehensively covered in this book. All of the
mathematical formulas are consistently developed from theorems and
linked with physics, which provides theoretical understanding and
further interest in wave dynamics. This is an ideal graduate-level
textbook or reference for engineers and researchers in the fields
of fluid and wave mechanics, coastal and ocean engineering.
