The author has provided the reader with comprehensive coverage of ship hydrodynamics with a focus on numerical methods now in use. The book provides a global overview of experimental and numerical methods for ship resistance and propulsion, manoeuvring and seakeeping. As boundary element techniques are now in standard use, these are covered in sufficient detail for independent code development.

The book is divided into seven chapters. Chapter one contains an overview of problems and approaches, including the basics of model and full scale testing. An introduction to computational fluid dynamics is given, including a discussion of applications.

The next four chapters cover the subjects: propellers, resistance and propulsion, seakeeping and manoeuvring. These chapters present basic methods, such as model testing, extrapolation to full scale, and procedures for design. Substantial parts of each chapter include numerical methods and their applications. The last two chapters are devoted to boundary element methods for resistance and seakeeping.

At first the equations and linearized boundary conditions are derived describing the non-viscous free surface water waves, with special attention to the combination of steady and non-steady flow fields. Then some simple kinds of free wave solutions are derived, such as plane waves and cylindrical waves. For several situations, steady and unsteady, the source singularity function is derived.

Water Waves and Ship Hydrodynamics (eBook, PDF)

With the enhanced ship hydrodynamic in Xicheng Canal, the shipgenerated waves are the main factor inducing turbidity in the water column and damages of the channel revetments. In this study, to clarify the characteristics of ship-generated waves in Xicheng Canal, field observations and numerical analysis were carried out. The field observations were conducted at a straight section of Xin xiagang River and the ship-generated waves model is established based on depth averaged non-linear shallow water NLSW equations. The water level fluctuations at different wave gauges calculated by Delft3D-FLOW model agree fairly well with the observed data.

The shallow-water wave equations of Boussinesq type are used to simulate the ship waves at subcritical, transcritical, and supercritical speeds. An implicit difference method based on the Crank-Nicholson scheme is applied for the time and space discretization. The associated finite-difference equation system is then iteratively solved with controllable accuracy. To approximate the flow generated by a slender ship the technique of matched asymptotic expansions is used. Satisfactory agreement between calculations and model experiments is achieved for wave resistance, sinkage and trim as well as for wave profiles in the tank.

An improved method to measure diffraction and radiation waves around a ship model running in waves at forward speed is proposed. Measured wave pattern especially with blunt bow and shallow draft ships is used to investigate validity of an analytical method to predict the diffraction and radiation waves and added resistance of a ship. We are developing more and more sophisticated analytical method to understand and predict realistic nonlinear hydrodynamics of ships in waves.
