Computational Flow Modeling for Chemical Reactor Engineering - Original PDF
نویسندگان: خلاصه: This book describes how modeling fluid flow in chemical reactors may offer solutions that improve design, operation, and performance of reactors. Chemical reactors are any vessels, tubes, pipes, or tanks in which chemical reactions take place. Computational Flow Modeling for Chemical Reactor Engineering will show the reactor engineer how to define the specific roles of computational flow modeling, select appropriate tools, and apply these tools to link reactor hardware to reactor performance. Overall methodology is illustrated with numerous case studies.Industry has invested substantial funds in computational flow modeling which will pay off only if it can be used to realize significant performance enhancement in chemical reactors. No other single source exists which provides the information contained in this book
Elastomer Blends and Composites: Principles, Characterization, Advances, and Applications - Original PDF
نویسندگان: خلاصه: Elastomer Blends and Composites: Principles, Characterization, Advances, and Applications presents the latest developments in natural rubber and synthetic rubber-based blends and nanocomposites, with a focus on current trends, future directions and state-of-the-art applications. The book introduces the fundamentals of natural rubber and synthetic rubbers, outlining synthesis, structure, properties, challenges and potential applications. This is followed by detailed coverage of compounding and formulations, manufacturing methods, and preparation of elastomer-based blends, composites, and nanocomposites. The next section of the book focuses on properties and characterization, examining elasticity, spectroscopy, barrier properties, and rheological, morphological, mechanical, thermal, and viscoelastic behavior, and more. This is a highly valuable resource for researchers and advanced students in rubber (or elastomer) science, polymer blends, composites, polymer science, and materials science and engineering, as well as engineers, technologists, and scientists working with rubber-based materials for advanced applications.
Elastomer Stereospecific Polymerization (Advances in Chemistry Series, Volume 052) - PDF
نویسندگان: خلاصه: Addition polymerization, initiated by organometallic compounds, has in recent years aroused widespread interest mainly because of the stereospeciflc character of many of these systems. It soon became apparent that the chain propagation reaction in these systems differed markedly from that of the wellknown free radical polymerizations in that it involved an orientation of the incoming monomer instead of a more random reaction. However, elucidating the detailed mechanism of this important step has been difficult owing to lack of knowledge about the exact structure of the organometallic compound as well as the heterogeneous nature of most such systems. The available knowledge of stereoregular polymerization (1), anionic propagation kinetics (13), and organolithium polymerization (2) has recently been reviewed. Based on presently available knowledge, therefore, it is now possible to sketch some general guide lines toward a better understanding of these phenomena.
Severe Plastic Deformation: Methods, Processing and Properties - PDF
نویسندگان: خلاصه: All materials are composed of atoms. Depending on the order in which the atoms are arranged with one another, solid material can be classified into crystalline and noncrystalline or amorphous materials. In crystalline materials, the atoms are arranged in a repetitive or periodic array over large atomic distances, while in amorphous materials this long-range atomic order is absent. The crystalline metals with different crystal structures, such as face-centered cubic, hexagonal closed pack, or bodycentered cubic, are divided into two categories: single crystal and polycrystalline.
Molding Simulation: Theory and Practice - Original PDF
نویسندگان: خلاصه: This practical introductory guide to injection molding simulation is aimed at both students and practicing engineers. It offers ways to innovate and improve part design and molding processes, which are essential for efficient manufacturing. This user-friendly book uses a case-study-based approach that is enhanced by many illustrations in full color. The book is divided into three parts. Part I introduces the fundamentals of injection molding, focusing on the factors governing molding quality and how molding simulation methodology is developed. Part II introduces CAE verification of design, a valuable tool for both part and mold designers. Part III introduces research and development in innovative molding, illustrating how CAE is applied to advanced molding techniques.
The History of Chile - Original PDF
نویسندگان: خلاصه: Within Chile is the driest desert in the world, the highest mountain range in the hemisphere, temperate rainforests, and a piece of Antarctica. In all these areas Chileans have created unique communities and, together, a vibrant nation. Chile's history mirrors its geographic variety. From its pre-colonial period, to its days as a Spanish colony, through its many independent governments, Chile has long been a land of crises and controversy. Beginning with a survey of the land, people, and current government of Chile, the book traces the chronological story of the country. Ten chapters follow the details of Chilean history from the indigenous peoples to the democratic transition after the Pinochet dictatorship. This is the perfect starting point for students and travelers interested in the history and people of Chile.
The Chile Reader: History, Culture, Politics - Original PDF
نویسندگان: خلاصه: The Chile Reader makes available a rich variety of documents spanning more than five hundred years of Chilean history. Most of the selections are by Chileans; many have never before appeared in English. The history of Chile is rendered from diverse perspectives, including those of Mapuche Indians and Spanish colonists, peasants and aristocrats, feminists and military strongmen, entrepreneurs and workers, and priests and poets. Among the many selections are interviews, travel diaries, letters, diplomatic cables, cartoons, photographs, and song lyrics. Texts and images, each introduced by the editors, provide insights into the ways that Chile's unique geography has shaped its national identity, the country's unusually violent colonial history, and the stable but autocratic republic that emerged after independence from Spain. They shed light on Chile's role in the world economy, the social impact of economic modernization, and the enduring problems of deep inequality. The Reader also covers Chile's bold experiments with reform and revolution, its subsequent descent into one of Latin America's most ruthless Cold War dictatorships, and its much-admired transition to democracy and a market economy in the years since dictatorship.
