Free Download Turbopumps and Pumping Systems by S. Ahmad Nourbakhsh (Prof.Dr.Ir), Baron Andre Jaumotte (Prof.Dr.Ir), Charles Hirsch (Prof.Dr.Ir), Hamideh B. Parizi (PhD.,P.Eng.em)

Pumps are one of the mechanical devices that are widely used in many industries throughout the world. Turbopumps which are common types of pumps are used mainly for transporting water in agricultural units, industrial processes, cooling and heating systems, and power plants. But their application is not limited only for h- dling water. Turbopumps can be used for transporting oil products in oil and gas industries and re neries, as well as byproductsin pulp and paper industry, food and beverage in food industry, and contaminated water in sewage systems. Because of the versatility of pump usage, the numberof turbopumpsin operation worldwide is very large and as a result the total energy consumption of these units can be considerable. To reduce the energy consumption by turbopumps, it is imp- tant to increase the ef ciency of the pumps, as well as the system they are working in. The pump manufacturing companies and design engineers are constantly trying to improve the performances of pumps by designing more ef cient pumps and by using the latest technologies available in terms of design software, new developed materials, and state of the art manufacturing tools. Today, computational uid - namics and sophisticated design software tools help designers to optimize the uid ow inside the pumps and to design different pump elements with better hydraulic ef ciencies. However, the operation of turbopumps can be optimized a well by effectively using proper pumps and designing ef cient piping systems.

Free Download Trends in Statistical Codicology by Marilena Maniaci
English | PDF,EPUB | 2021 | 780 Pages | ISBN : 3110711427 | 114.9 MB
The application of statistical techniques to the study of manuscript books, based on the analysis of large data sets acquired through the archaeological observation of manuscripts, is one of the most original trends in codicological research, aiming not only to reconstruct on a sound basis the methods and processes used in book manufacture and their tendential evolution in space and time, but also to interpret them as the result of a dynamic interplay between various and often incompatible needs (of cultural, technical, social and economic nature) that book artisans had to reconcile in the best possible way.

Free Download Tissue Mechanics by Stephen C. Cowin, Stephen B. Doty
English | PDF (True) | 2007 | 685 Pages | ISBN : 0387368256 | 29.8 MB
I was delighted when I learned in the fall of 2005 that Steve Cowin was working on a textbook in biomechanics. Steve and I were in the same department at Tulane University in the 1970s, and under his influence I learned the beauty and power of continuum mechanics as a means to better understand the musculoskeletal system. When I began teaching courses in biomechanics during that decade, it was natural to teach the material from a continuum mechanics persp- tive. Over the years I have used a variety of continuum mechanics texts, but, for the most part, I have had to find the biomedical examples I used directly from the research literature. I have now had a chance to review a draft of Tissue Mechanics by Cowin and Doty, and it exceeds my high expectations. The material includes a rigorous and comprehensive introd- tion to continuum mechanics oriented toward biomechanics. Indeed, all of the foundation t- ics for continuum models of biological materials are covered. This material is illustrated through applications to the hard and soft tissues of the human body. Steve Cowin is now one of the leading researchers in the mechanics of bone, so one would expect the chapters on bone tissue and bone tissue adaptation to be of a very high order. But the presentation on collagen and cartilage mechanics is also excellent. Their presentation of finite deformation mechanics and its application to tendons and ligaments is one of the most accessible in the literature.

Free Download Three-Dimensional Contact Problems by V. M. Alexandrov , D. A. Pozharskii
English | PDF (True) | 2001 | 422 Pages | ISBN : 1402003870 | 41.3 MB
A systematic treatment, based on Green's functions and integral equations, is given to the analytical and numerical methods and results for a great number of 3-D contact problems for elastic bodies. Semi-bounded elastic bodies (layer, cylinder, space with cylindrical or spherical cavity, 3-D wedge, special cases of which are half- and quarter-spaces, cone) and finite elastic bodies (circular plate, finite cylinder, spherical layer, spherical lens, sphere) are considered. Methods introduced in the book can also be applied in fracture mechanics, hydrodynamics, electrostatics, thermodynamics and diffusion theory, continuum mechanics, and mathematical physics, as well as by engineers and students in mathematics, mechanics, and physics.

Free Download Thermomechanics of Continua by Krzysztof Wilmański
English | PDF | 1998 | 283 Pages | ISBN : 3540641416 | 39.7 MB
The notion of continuum thermodynamics, adopted in this book, is primarily understood as a strategy for development of continuous models of various physical systems. The examples of such a strategy presented in the book have both the classical character (e. g. thermoelastic materials, viscous fluids, mixtures) and the extended one (ideal gases, Maxwellian fluids, thermoviscoelastic solids etc. ). The latter has been limited intentionally to non-relativistic models; many important relativistic applications of the true extended thermodynamics will not be considered but can be found in the other sources. The notion of extended thermodynamics is also adopted in a less strict sense than suggested by the founders. For instance, in some cases we allow the constitutive dependence not only on the fields themselves but also on some derivatives. In this way, the new thermodynamical models may have some features of the usual nonequilibrium models and some of those of the extended models. This deviation from the strategy of extended thermodynamics is motivated by practical aspects; frequently the technical considerations of extended thermodynamics are so involved that one can no longer see important physical properties of the systems. This book has a different form from that usually found in books on continuum mechanics and continuum thermodynamics. The presentation of the formal structure of continuum thermodynamics is not always as rigorous as a mathematician might anticipate and the choice of physical subjects is too disperse to make a physicist happy.

Free Download Thermodynamics of Materials with Memory: Theory and Applications by Giovambattista Amendola , Mauro Fabrizio , John Murrough Golden
English | PDF (True) | 2012 | 576 Pages | ISBN : 1489995870 | 4.6 MB
This is a work in four parts, dealing with the mechanics and thermodynamics of materials with memory, including properties of the dynamical equations which describe their evolution in time under varying loads. The first part is an introduction to Continuum Mechanics with sections dealing with classical Fluid Mechanics and Elasticity, linear and non-linear. The second part is devoted to Continuum Thermodynamics, which is used to derive constitutive equations of materials with memory, including viscoelastic solids, fluids, heat conductors and some examples of non-simple materials. In part three, free energies for materials with linear memory constitutive relations are comprehensively explored. The new concept of a minimal state is also introduced. Formulae derived over the last decade for the minimum and related free energies are discussed in depth. Also, a new single integral free energy which is a functional of the minimal state is analyzed in detail. Finally, free energies for examples of non-simple materials are considered. In the final part, existence, uniqueness and stability results are presented for the integrodifferential equations describing the dynamical evolution of viscoelastic materials. A new approach to these topics, based on the use of minimal states rather than histories, is discussed in detail. There are also chapters on the controllability of thermoelastic systems with memory, the Saint-Venant problem for viscoelastic materials and on the theory of inverse problems.
