Available in PDF, EPUB and Kindle. Book excerpt: Atomization characteristics of an impinging jet injector were studied over a range of injection velocities and back-pressures typical of liquid rocket injectors. Sheet breakup length was measured by strobe light imaging and was found to decrease with increasing injection velocity and chamber pressure. The experimentally measured breakup length was compared to linear stability theory and agreement was found to improve with increasing chamber gas density. At low chamber pressures, disturbances due to impact waves were believed to be the primary breakup mechanism. Measurements of droplet size distribution were made with a combination of laser diffraction and droplet imaging instruments. Droplet size was found to be a highly non-linear function of chamber pressure and axial distance from the impingement point. Sauter mean diameter was found to decrease with increasing chamber pressure and axial distance. Secondary atomization was believed to be the breakup mechanism responsible for this dependence. The width of the droplet size distribution was also found to be a function of chamber pressure.

This book was released on 1970 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was completed to examine the influence of injector design changes on the resultant drop size for like impinging doublet injectors. The variables studied are injection velocity, orifice diameter, impingement angle, stream alignment, orifice length to diameter ratio, and orifice surface finish. Droplet data were obtained using water as the propellant simulant in conjunction with a back-lighted photographic technique. It was found that no detectable change in drop size resulted from changes in orifice L/D or orifice surface finish within the ranges investigated. Stream misalignment was found to increase drop size when the other injector parameters remained constant. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Annotation Since the invention of the V-2 rocket during World War II, combustion instabilities have been recognized as one of the most difficult problems in the development of liquid propellant rocket engines. This book is the first published in the United States on the subject since NASA's Liquid Rocket Combustion Instability (NASA SP-194) in 1972. In this book, experts cover four major subject areas: engine phenomenology and case studies, fundamental mechanisms of combustion instability, combustion instability analysis, and engine and component testing. Especially noteworthy is the inclusion of technical information from Russia and China--a first.

Available in PDF, EPUB and Kindle. Book excerpt: This book gathers the proceedings of the Fifth Symposium on Hybrid RANS-LES Methods, which was held on March 19-21 in College Station, Texas, USA. The different chapters, written by leading experts, reports on the most recent developments in flow physics modelling, and gives a special emphasis to industrially relevant applications of hybrid RANS-LES methods and other turbulence-resolving modelling approaches. The book addresses academic researchers, graduate students, industrial engineers, as well as industrial R&D managers and consultants dealing with turbulence modelling, simulation and measurement, and with multidisciplinary applications of computational fluid dynamics (CFD), such as flow control, aero-acoustics, aero-elasticity and CFD-based multidisciplinary optimization. It discusses in particular advanced hybrid RANS-LES methods. Further topics include wall-modelled Large Eddy Simulation (WMLES) methods, embedded LES, and a comparison of the LES methods with both hybrid RANS-LES and URANS methods. Overall, the book provides readers with a snapshot on the state-of-the-art in CFD and turbulence modelling, with a special focus to hybrid RANS-LES methods and their industrial applications.

Available in PDF, EPUB and Kindle. Book excerpt: Uncover Effective Engineering Solutions to Practical Problems With its clear explanation of fundamental principles and emphasis on real world applications, this practical text will motivate readers to learn. The author connects theory and analysis to practical examples drawn from engineering practice. Readers get a better understanding of how they can apply these concepts to develop engineering answers to various problems. By using simple examples that illustrate basic principles and more complex examples representative of engineering applications throughout the text, the author also shows readers how fluid mechanics is relevant to the engineering field. These examples will help them develop problem-solving skills, gain physical insight into the material, learn how and when to use approximations and make assumptions, and understand when these approximations might break down. Key Features of the Text * The underlying physical concepts are highlighted rather than focusing on the mathematical equations. * Dimensional reasoning is emphasized as well as the interpretation of the results. * An introduction to engineering in the environment is included to spark reader interest. * Historical references throughout the chapters provide readers with the rich history of fluid mechanics.
Download or read book Physics and Engineering of New Materials written by Do Tran Cat and published by Springer Science & Business Media. This book was released on 2009-01-01 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the majority of the contributions to the Tenth German-Vietnamese Seminar on Physics and Engineering (GVS10) that took place in the Gustav- Stresemann-Institut (GSI) in Bonn from June 6 to June 9, 2007. In the focus of these studies are the preparation and basic properties of new material systems, related investigation methods, and practical applications. Accordingly the sections in this book are entitled electrons: transport and confinement, low-dimensional systems, magnetism, oxidic materials, organic films, new materials, and methods. The series of German-Vietnamese seminars was initiated and sponsored by the Gottlieb Daimler- and Karl Benz -Foundation since 1998 and took place alt- nately in both countries. These bilateral meetings brought together top-notch senior and junior Vietnamese scientists with German Scientists and stimulated many contacts and co-operations. Under the general title “Physics and Engine- ing” the programs covered, in the form of keynote-lectures, oral presentations and posters, experimental and theoretical cutting-edge material-physics oriented topics. The majority of the contributions was dealing with modern topics of material science, particularly nanoscience, which is a research field of high importance also in Vietnam. Modern material science allows a quick transfer of research results to technical applications, which is very useful for fast developing countries like Vietnam. On the other hand, the seminars took profit from the strong cro- fertilization of the different disciplines of physics. This book is dedicated to the tenth anniversary of the seminars and nicely shows the scientific progress in Vietnam and the competitive level reached.
