The design and construction of rotating machinery operating at supercritical speeds was, in the 1920s, an event of revolutionary importance for the then new branch of dynamics known as rotor dynamics. In the 1960s, another revolution occurred: In less than a decade, imposed by operational and economic needs, an increase in the power of turbomachinery by one order of magnitude took place. Dynamic analysis of complex rotor forms became a necessity, while the importance of approximate methods for dynamic analysis was stressed. Finally, the emergence of fracture mechanics, as a new branch of applied mechanics, provided analytical tools to investigate crack influence on the dynamic behavior of rotors.

The scope of this book is based on all these developments.No topics related to the well-known classical problemsare included, rather the book deals exclusively with modern high-power turbomachinery.

Since the 1970's, an increasing amount of specialized research has focused on the problems created by instability of internal flow in hydroelectric power plants. However, progress in this field is hampered by the inter disciplinary nature of the subject, between fluid mechanics, structural mechanics and hydraulic transients. Flow-induced Pulsation and Vibration in Hydroelectric Machinery provides a compact guidebook explaining the many different underlying physical mechanisms and their possible effects. Typical phenomena are described to assist in the proper diagnosis of problems and various key strategies for solution are compared and considered with support from practical experience and real-life examples. The link between state-of the-art CFD computation and notorious practical problems is discussed and quantitative data is provided on normal levels of vibration and pulsation so realistic limits can be set for future projects. Current projects are also addressed as the possibilities and limitations of reduced-scale model tests for prediction of prototype performance are explained. Engineers and project planners struggling with the practical problems will find Flow-induced Pulsation and Vibration in Hydroelectric Machinery to be a comprehensive and convenient reference covering key topics and ideas across a range of relevant disciplines.

This book, which is published in two volumes, studies heat transfer problems by modern numerical methods. Basic mathematical models of heat transfer are considered. The main approaches, to the analysis of the models by traditional means of applied mathematics are described. Numerical methods for the approximate solution of steady- and unsteady state heat conduction problems are discussed. Investigation of difference schemes is based on the general stability theory. Much emphasis is put on problems in which phase transitions are involved and on heat and mass transfer problems. Problems of controlling and optimizing heat processes are discussed in detail. These processes are described by partial differential equations, and the main approaches to numerical solution of the optimal control problems involved here are discussed. Aspects of numerical solution of inverse heat exchange problems are considered. Much attention is paid to the most important applied problems of identifying coefficients and boundary conditions for a heat transfer equation. The first volume considered the mathematical models of heat transfer, classic analytical solution methods for heat conduction problems, numerical methods for steady-state and transient heat conduction problems, and phase change problems. In this second volume, we present solution techniques for complicated heat transfer problems (radiation, convection, thermoelasticity, thermal process control and inverse problems) as well as some examples of solving particular heat transfer problems.

The EUCOMES08, Second European Conference on Mechanism Science is the second event of a series that has been started in 2006 as a conference activity for an European community working in Mechanism Science. The ?rst event was held in Obergurgl, Austria in 2006. This year EUCOMES08 Conference has come to Cassino in Italy taking place from 17 to 20 September 2008. TheaimoftheEUCOMESConference istobringtogetherEuropean researchers, industry professionals and students from the broad ranges of disciplines referring to Mechanism Science, in an intimate, collegial and stimulating environment. In this second event we have received an increased attention to the initiative, as canbeseenbythefactthattheEUCOMES08Proceedingswillcontaincontributions by authors even from all around the world. This means also that there is a really interest to have not only a conference frame but even a need of aggregation for an European Community well identi?ed in Mechanism Science with the aim to strengthen common views and collaboration activities among European researchers and institutions. I believe that a reader will take advantage of the papers in these Proceedings with further satisfaction and motivation for her or his work. These papers cover the wide ?eld of the Mechanism Science. The program of EUCOMES08 Conference has included technical sessions with oral presentations, which, together with informal conversations during the social program, have enabled to offer wide opportunities to share experiences and discuss scienti?c achievements and current trends in the areas encompassed by the EUCOMES08 conference.

Gas controls and air-gas ration equipment are considered which is particularly relevant to those responsible for designing, servicing, maintaining and updating gas fired plant for safety and efficience. Individual chapters focus on gas supply, electrical power generation including combined heat and power and all aspects of instrumentation and measurment. Safety is a theme running throughout the book and all relevant references are made to the British Gas Standards and Codes of Practice.

This book can simply be summed up as the thermodynamics 'bible' for mechanical engineering students. It gives the fundamentals of engineering thermodynamics and their application to particular fluids and the ways in which work and heat transfer are affected.
Part I is devoted to the principles of thermodynamics, Part II to applications of the principles to particular fluids, and Parts III and IV respectively to ways in which work and heat transfers are effected. This scheme leaves it open to the lecturer to choose any preferred order of presentation, but also provides the student with a book which enables principle to be distinguished from application.

The majority of 0D/1D knock models available today are known for their poor accuracy and the great effort needed for their calibration. Alexander Fandakov presents a novel, extensively validated phenomenological knock model for the development of future engine concepts within a 0D/1D simulation environment that has one engine-specific calibration parameter. Benchmarks against the models commonly used in the automotive industry reveal the huge gain in knock boundary prediction accuracy achieved with the approach proposed in this work. Thus, the new knock model contributes substantially to the efficient design of spark ignition engines employing technologies such as full-load exhaust gas recirculation, water injection, variable compression ratio or lean combustion. About the Author Alexander Fandakov holds a PhD in automotive powertrain engineering from the Institute of Internal Combustion Engines and Automotive Engineering (IVK) at the University of Stuttgart, Germany. Currently, he is working as an advanced powertrain development engineer in the automotive industry.
