Free-Surface Flow: Computational Methods presents a detailed analysis of numerical schemes for shallow-water waves. It includes practical applications for the numerical simulation of flow and transport in rivers and estuaries, the dam-break problem and overland flow. Closure models for turbulence, such as Reynolds-Averaged Navier-Stokes and Large Eddy Simulation are presented, coupling the aforementioned surface tracking techniques with environmental fluid dynamics. While many computer programs can solve the partial differential equations describing the dynamics of fluids, many are not capable of including free surfaces in their simulations.
Although many books have been written on computational fluid dynamics (CFD) and many written on combustion, most contain very limited coverage of the combination of CFD and industrial combustion. Furthermore, most of these books are written at an advanced academic level, emphasize theory over practice, and provide little help to engineers who need to use CFD for combustion modeling.
Flow-induced vibrations and noise continue to cause problems in a wide range of engineering applications ranging from civil engineering and marine structures to power generation and chemical processing. These proceedings bring together more than a hundred papers dealing with a variety of topics relating to flow-induced vibration and noise. The contents of this work constitute a mix of investigations by those working on the mechanisms of vibration and means of their alleviation, and studies by those in industry who draw on the present state of knowledge of these mechanisms to avoid or solve flow-induced vibration and noise problems in industrial applications.

This is a comprehensive work of reference for engineers dealing with the hydraulic problems that occur along coastlines and estuaries and in harbours. This branch of engineering has experienced rapid and profound changes since the 1960s due to the introduction of powerful computer modelling techniques. The book presents concise reviews of key topics on these techniques as well as the traditional civil engineering aspects of design and construction of coastal and maritime works. The powerful tools which are now available for computational and numerical modelling of hydraulic systems have to a considerable extent replaced physical models as the most appropriate means of investigating and selecting economic design options. This development has taken place alongside a greater understanding of the transport processes of granular and cohesive sediments, and an increasing concern with the environmental impact of engineering works. At the design stage, the engineer now commonly has to demonstrate the impact of the proposed works on the natural/watery environment. The chapters are presented under seven main headings: the physical environment; the scientific background; numerical tools and t
This book provides an introduction to the subject of turbulence modelling in a form easy to understand for anybody with a basic background in fluid mechanics, and it summarizes the present state of the art. Individual models are described and examined for the merits and demerits which range from the simple Prandtl mixing length theory to complex second order closure schemes.

This work provides comprehensive guidance on maintaining old waterfront walls, especially gravity walls constructed with stone masonry, brick blocks or mass concrete. It should be of use to engineers and owners responsible for such structure. Many existing waterfront structures (harbour and dock walls, breakwaters, seawalls, flood defences, skin walls, bridge piers and abutments) are crucial parts of industrial or environmental facilities. Many date back to the 19th century and earlier, and information on their design and construction is often incomplete. They are often massive structures, and the problems of working over or under water and on the buried back of the wall mean that they are difficult and expensive to investigate and maintain, yet they represent substantial capital assets and appropriate management and maintenance are essential. This work draws together a wealth of information and experience on the types of wall that were constructed up to the earlier part of this century. It includes numerous drawings and illustrations of these walls and reviews their performance. It goes on to identify and describe the most suitable techniques available for their inspection, struct
This monograph provides the practising engineer with a concise overview of the methods of water diversion and exclusion or removal of sediment from the diverted water. The emphasis is on flow features and the associated conveyance of sediments. |
