Rudder Propeller and Hull Interaction by RANS

   In ail attempt to increase the safety at sea more attention has been focused on the requirements of the education of the officers sailing the ships and of the maneuverability of the sliips. Tliis has of course increased the interest in the numerical maneuvering simulators, which are a strong tool for investigation of the maneuverability of the ship and for the training of the crew members. Consequently, the increased interest lias resulted in stronger requirements of the quality, accuracy and reliability of the maneuvering models behind the simulators. The simulators are doing well today, but there are still areas where additional knowledge could be useful to improve the models. One of these areas is the interaction between the rudder, propeller and hull, which plays an important role for successful modeling of the maneuvering problem. Today the state of the art in maneuvering simulation covers the full mission simulators based on numerical solution of the equations of motion in conjunction with experimental hydrodynamic data which is mainly determined by means of captive model testing techniques like the planar motion mechanism (PMM). A study of the maneuvering model and the PMM model testing technique applied to the data generation revealed that a comprehensive set of experimental input data was required in order to perform a maneuvering simulation and model the rudder, propeller and hull interaction.

Shaft Grounding Rings - Protecting VFD Driven Motors from Bearing Currents

   When pulse width modulation (PWM) Variable Frequency Drives (VFDs) were developed using insulated gate bipolar transistors (IGBTs), this new technology was used to control electric induction motors in industrial and commercial applications. The advantages were obvious: Torque and motor speed could now be precisely controlled to optimize both process and energy requirements, The potential to save energy by operating motors at only the needed speed while maintaining torque requirements could potentially result in a 20% to 50% energy savings, Processes could be optimized and controlled by computer processing systems to achieve productivity increases or energy savings.

Dual-Fuel Diesel Engines

   The rate of consumption of the energy resources available continues to increase in spite of the significant progress being made to enhance the efficiency of their usage. Contributions to this increase in consumption include the rise in world population, improvements in the average standard of living, and the increase in average life expectancy. It is expected that the combustion of fossil fuels will continue to be the prime source to rely on for energy for some time to come. This will be constrained, however, by the continued depletion of crude petroleum resources of quality, the need for ever-cleaner exhaust emissions, and the rapid progress being made in the development of renewable resources. On the other hand, it is becoming increasingly evident, especially more recently, that the availability of natural gas, as well as other gaseous fuels, is increasing. This has come about mainly as a result of the improvements in the long-range transportation of gas and the increased availability of unconventional sources, such as those of shale gas, biogases, and coal bed-derived gases. Moreover, the increased exploitation of unconventional resources of liquid hydrocarbon fuels, such as tar sands, is bringing with it the potential production of large amounts of gaseous fuel mixtures, albeit of varied quality and having lower heating values than those of the conventional processed pipeline natural gas. On this basis, there are many opportunities to increasingly exploit such gaseous fuel resources while at the same time economizing on the consumption of other nonrenewable type liquid fossil fuel resources. Such approaches would need to develop further new means for the production of power while continuing the overall reduction of exhaust emissions, including those associated with their contribution to global warming.

Modelling and Observation of Exhaust Gas Concentrations for Diesel Engine Control

   In spite of the economic crisis of transport sectors such as the aerospace or naval, the automotive sector is facing a really challenging time. The trends in this sector during the past years had been focused on minimizing the pollutants, namely NOs, CO, HC or PM. However, the efforts in the next years are moving towards the C02 reduction, and thus minimizing the fuel consumption without worsening the pollutants. In the case of gasoline engines, the emissions problem is relatively solved since years by the three-way catalyst but for diesel, the use of different after-treatment systems as well as new combustion systems and control improvements are necessary. At the same time, the introduction of new fuel types and the development of the electric or hybrid vehicles introduce indeed new possibilities to the engineers. The diesel engine requires a renewal of the number of information sources available in order to monitor and control all the variables that affect the correct performance of this complex system. A good example is the on-board diagnostics algorithms necessary to monitor the NOx emissions, required for the urea dosing of the selective catalyst reduction systems or useful for the development of direct NOs control. Within this framework, this book intends to give solutions to real problems on the topic of the online estimation of the exhaust engine variables in diesel engines. The reader will find a number of methods and algorithms that cover the main possibilities for inferring the exhaust variables on-board...

Pumping Machinery Theory and Practice

   The consumption of energy taking place in pumping systems accounts for approximately twenty per cent of the world's electrical energy demand. Moreover, the operational cost of pumping machinery tar outweighs their capital cost. Accordingly, engineers strive for optimum equipment performance for achieving economic operation, and a thorough understanding of the components and operating principles of these machines will provide an opportunity to dramatically reduce energy, as well as operational and maintenance costs. Reducing energy consumption will also complement the current thrust towards protecting our environment. This book is intended to be a basic reference on theoretical foundation and applications of various types of pumping machinery. In view of the great importance of pumps and compressors in almost every engineering system, this book presents the fundamental concepts underlying the flow processes taking place in these machines and the transformation of mechanical energy into fluid power. Special emphasis is given to basic theoretical formulation and design considerations of pumps and compressors in addition to improving problem-solving skills. This is achieved through the presentation of solved examples of applied nature using analytical means and/or basic engineering practices. The book consists of ten chapters covering two main themes: the first smoothly introduces the essential terminology, basic principles, design considerations, and operational-type problems in pumping machinery. This part is supported by a good number of worked examples plus problems at the end of each chapter for the benefit of senior undergraduate students and junior engineers. This is considered a key feature of this book because other books in this area rarely provide enough worked problems and exercises. The second theme focuses on advanced topic such as two-phase flow pumping systems targeting practicing field engineers and introductory research scientists.

Compressed Air Operations Manual

   The purpose of this book is to provide a basic understanding of the compressed air systems, equipment, and technologies that are available on the market today. You might have many years of experience with a specific compression system, but the catalogs and sales literature just aren't providing you with the information you need. Maybe you've just been assigned the compression system as part of your responsibilities and you have no experience whatsoever with this type of equipment. Oftentimes, the compressors are the bastard child of a company's capital equipment and no one in particular is responsible for them. If you head up the company's maintenance department, the compressors probably fall under your responsibilities. You may be a salesman who works with pneumatic-powered equipment and, from time to time, are asked to comment on your customer's compression systems. In any case, this book will give you the baseline information that will allow you to make well-informed decisions about specifying, expanding, or assessing a compression system. Like many technical people, I felt that I had a clear conceptual understanding of air compression, I mean, what's to know? You suck in some air, you smash it into a tank. Simple! I even built an air compressor from an old auto AC pump and a piece of pipe when I was in high school.юю

The Coen & Hamworthy Combustion Handbook

   The last Coen & Hamivorthy Combustion Handbook was written by Arthur H. Light in 1920.' In the late 1980s, Coen authorized the publication of a new combustion handbook at the request of its customers, but day-to-day work never allowed time for the book. The origins of this book started during a business trip. In early 2000, one of the editors (Steve) was on a trip to visit a major Coen customer with a young Coen application engineer. During dinner, the engineer told Steve a story of a number of engineers debating the units of molecular weight for hours. It was at this moment that Steve decided a unique kind of book was needed that did not exist for combustion engineers. The book needed to be all inclusive and cover the very basics in building block form up to more complex combustion topics for everyone involved in combustion systems to use. This book is designed for all engineers and professionals involved in the field of industrial and utility combustion systems. It is roughly divided into two parts, consisting of a total of 17 chapters, sequentially covering relevant and important combustion engineering basics and then specific computations and applications. Each chapter is roughly organized from simple to more complex, thus allowing the reader to absorb as much as they may need before moving on to the next chapter. Practical examples are also included.

Centrifugal Pumps

   The pumps, icluding centrifugal type pumps, are widely presented in ship hull systems. It means that every professional desling with the design of pumps has to have very good theoretical knowledge and fully understand how they work. But that is not enough, and they should be familiar with the practical application of pumps and engineering correlations for flow phenomena. This book is intended to be of use to pump designers as well as crew members dealing with the day-to-day operation and maintenance of pumps. The chapters of this publication cover such interesting and important topics as various pump types and their performance data, fluid dynamic principles, physical concepts and pump hydraulics, various performance characteristics, partload operation, cavitation and suction capability, design of the various hydraulic components, vibration and noise, hydraulic forces, pump operation, general characteristics of turbine operation, selection of materials exposed to high flow velocities, influence of the medium, pump selection and quality considerations, and pump testing.

Maritime Engineering and Technology

   Here is a very good compilation of the articles related to the maritime engineering and maritime technology. There are nine main parts in this book covering such areas as ship control and propulsion, ship design, onboard systems, ship traffic, resk and reliability, ship structures, ship dynamics and hydrodynamics, renewable energy, wave and wind modeling. For more than twenty-five years, the Naval Architecture and Marine Engineering branch of the Portuguese Association of Engineers and the Centre for Marine Technology and Engineering of the Instituto Superior Tecnico, Technical University of Lisbon, have been organizing national conferences on Marine Engineering and Naval Architecture. Such meetings had the objective of bringing together Portuguese professionals and giving them an opportunity to present and discuss the ongoing technical activities. They have been attended by up to 200 participants. The papers presented in these meetings have been collected in a series of books written in Portuguese. At the same time, as the conferences have become more mature, the international contacts have also increased and the industry became more international in such a way that the fact that the conference was in Portuguese started to hinder its further development with wider participation. Therefore, for the session that was planned for 2010, a decision was made to experiment with having also papers in English, mixed with the usual papers in Portuguese. The national meetings have normally taken place around the month of November but, given that IST was completing 100 years of existence in May 2011, another decision was made to postpone this Conference to 10-12 May 2011 so as to associate it also with the commemorations of the 100 years of IST...

Boiler Operator's Handbook

   This book is aimed to be used by boiler operators, operating engineers or stationary engineers by title, having enough theoretical knowledge and practical experience with operating boilers but would wishing to know moге and be able to operate their boiler plants wisely. The book is simple enough to be understood by beginner operators. This publication can also be used by the superintendent or manager who wants to have a reference to understand what his boiler plant operators are talking about. It would be fair to warn a reader that this book that it assumes a certain amount of experience and knowledge already exists. The day I mailed the contract for this book to the publisher I sat across a table from a boiler operator who said, "Why hasn't somebody written a book for boiler operators that isn't written for engineers?" I've tried to do it with this book, no high powered math and minimal technical jargon. There are two basic types of operators, those that put in their eight hours on shift while doing as little as possible and those that are proud of their profession and do their best to keep their plant in top shape and running order. You must be one of the latter and you should take pride in that alone...

Steam Generators and Waste Heat Boilers

   For over three decades, I was associated with boiler companies designing oil- and gas-fired custom package boilers and waste heat boilers that are in operation worldwide in chemical plants, refineries, cogeneration systems, and power plants. The boilers have been operating well and performing as predicted within the margin of measurement errors. As a specialist in thermal design of heat transfer equipment and out of interest, I would correlate field data from operating units with predicted performance to check the correction factors to be incorporated in heat transfer or gas pressure drop correlations that were used for designing the boilers. I would review operating data such as boiler exit gas temperature, steam generation, fuel input, gas pressure drop, evaporator, superheater performance, their tube wall temperatures, and other process-related parameters and compare the results with predicted data. Over the years this has helped me to fine-tune the calculation procedure and modify the correction factors used in the performance evaluation of various heat transfer surfaces. Through the publication of hundreds of articles during this period, I have also been sharing thermal design procedures for boilers and HRSGs with the engineering community. I have written a few books, the recent being Industrial Boilers and HRSGs, where the emphasis was on sizing and performance evaluation of steam generator and waste heat boiler components. For the past decade, since the publication of the cited book, I have been playing the role of a boiler consultant. The transformation from a boiler designer to a boiler consultant has been gratifying as I can interact with plant engineers worldwide and learn from them about various boiler performance issues and suggest modifications to solve boiler-related problems or improve their performance (the word boiler refers to a steam generator as well as a waste heat recovery unit). Many plant engineers or even consultants have no clue as to how a boiler should be evaluated before it is bought or what information should be obtained from boiler suppliers regarding its thermal performance aspects. They rely entirely on the sales pitch from boiler suppliers and buy it without giving any critical thought to its design from a thermal performance viewpoint. Purchasing a boiler is thought of as purchasing a commodity. When purchasing a steam generator or HRSG, plant engineers have to evaluate several factors keeping in mind that the life of a boiler is about 30 to 40 years and that the plant will have to face the consequence of any wrong decision for a long time...

Heat Pipe Design and Technology

   The heat pipe is probably one of the most remarkable achievements in the field of thermal physics and in heat transfer engineering during the course of this century because of its unique ability to transfer heat over large distances with minimal losses. Heat pipes are used mainly to protect the environment and to save energy and fuel. They have emerged as an effective thermal solution, particularly in high heat flux applications and in situations where there is a combination of nonuniform heat loading and limited airflow over the heat generating components, and weight or space constraints. This book will briefly introduce heat pipe technology and then highlight its basic applications for passive thermal control. Once a heat and mass transfer theory relevant to heat pipe performance have been reviewed, mathematical models can be developed for calculating heat transfer limitations in high temperature heat pipes, and heat transfer limitations and temperature gradient of low temperature heat pipes. Calculated results are compared with the available experimental data from various sources to increase confidence in the present math models. For the convenience of the users of the present theory, a few computer codes and their applications are mentioned and they are available from Galaxy Advanced Engineering. Inc. These codes are designed to handle interactive input from users of the codes as well as two computer programs for high- and low-temperature heat pipes respectively are reported. These programs enable the performance of heat pipes with wrapped-screen, rectangular-groove, or screen-covered rectangular-groove wick to be predicted. These codes are especially helpful in the design of steady-state heat pipe and are executable on Window/PC computing platforms.
