This book was released on 1983 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1979 the Propulsion and Energetics Panel of AGARD established a Working Group named WG 14 whose terms of reference were to study the averaging techniques used for non-uniform internal flows. This problem is relevant to gas turbine systems, in which the actual flows are usually heterogeneous and three-dimensional. Nevertheless, the test analysis and performance prediction methods are presently based upon simple one-dimensional models. Members of WG 14 first reviewed current practices as employed by research and development teams in various research establishments and industry. The Group also undertook a theoretical analysis of the relations which may be correctly applied to steady flows. Consequently it was possible to discuss and classify known averaging methods. The theoretical study concludes by proposing refinements to known methods and a new approach to averaging for use with engine components and propulsion system analysis. A large variety of possible averaging techniques were identified. Some were based on theoretical considerations, others were without justification except in their simplicity or common usage. All the averaging procedures were tested and compared by preparing a number of sample calculations in ducted flows, turbojet components and a complete propulsion system.

Download or read book Radial Flow Turbocompressors written by Michael Casey and published by Cambridge University Press. This book was released on 2021-06-10 with total page 790 pages. Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the theory and engineering practice that underpins the component design and analysis of radial flow turbocompressors. Drawing upon an extensive theoretical background and years of practical experience, the authors provide descriptions of applications, concepts, component design, analysis tools, performance maps, flow stability, and structural integrity, with illustrative examples. Features wide coverage of all types of radial compressor over many applications unified by the consistent use of dimensional analysis. Discusses the methods needed to analyse the performance, flow, and mechanical integrity that underpin the design of efficient centrifugal compressors with good flow range and stability. Includes explanation of the design of all radial compressor components, including inlet guide vanes, impellers, diffusers, volutes, return channels, de-swirl vanes and side-streams. Suitable as a reference for advanced students of turbomachinery, and a perfect tool for practising mechanical and aerospace engineers already within the field and those just entering it.
Download or read book Transition Location Effect on Shock Wave Boundary Layer Interaction written by Piotr Doerffer and published by Springer Nature. This book was released on 2020-07-30 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents experimental and numerical findings on reducing shock-induced separation by applying transition upstream the shock wave. The purpose is to find out how close to the shock wave the transition should be located in order to obtain favorable turbulent boundary layer interaction. The book shares findings obtained using advanced flow measurement methods and concerning e.g. the transition location, boundary layer characteristics, and the detection of shock wave configurations. It includes a number of experimental case studies and CFD simulations that offer valuable insights into the flow structure. It covers RANS/URANS methods for the experimental test section design, as well as more advanced techniques, such as LES, hybrid methods and DNS for studying the transition and shock wave interaction in detail. The experimental and numerical investigations presented here were conducted by sixteen different partners in the context of the TFAST Project. The general focus is on determining if and how it is possible to improve flow performance in comparison to laminar interaction. The book mainly addresses academics and professionals whose work involves the aerodynamics of internal and external flows, as well as experimentalists working with compressible flows. It will also be of benefit for CFD developers and users, and for students of aviation and propulsion systems alike.
