Book Shock Wave Boundary Layer Interactions

Download or read book Shock Wave Boundary Layer Interactions written by Holger Babinsky and published by Cambridge University Press. This book was released on 2011-09-12 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.

Book Analysis of the Interaction of a Weak Normal Shock Wave with a Turbulent Boundary Layer

Download or read book Analysis of the Interaction of a Weak Normal Shock Wave with a Turbulent Boundary Layer written by R. E. Melnik and published by . This book was released on 1974 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The method of matched asymptotic expansions is used to analyze the interaction of a normal shock wave with an unseparated turbulent boundary layer on a flat surface at transonic speeds. The theory leads to a three-layer description of the interaction in the double limit of Reynolds number approaching infinity and Mach number approaching unity. The interaction involves an outer, inviscid rotational layer, a constant shear-stress wall layer, and a blending region between them.

Book Turbulent Shear Layer Shock Wave Interactions

Download or read book Turbulent Shear Layer Shock Wave Interactions written by J. Delery and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was on a proposal of the late Professor Maurice Roy, member of the French Academy of Sciences, that in 1982, the General Assembly of the International Union of Theoretical and Applied Mechanics decided to sponsor a symposium on Turbulent Shear-Layer/Shock-Wave Interactions. This sympo sium might be arranged in Paris -or in its immediate vicinity-during the year 1985. Upon request of Professor Robert Legendre, member of the French Academy of Sciences, the organization of the symposium might be provided by the Office National d'Etudes et de Recherches Aerospatiales (ONERA). The request was very favorably received by Monsieur l'Ingenieur General Andre Auriol, then General Director of ONERA. The subject of interactions between shock-waves and turbulent dissipative layers is of considerable importance for many practical devices and has a wide range of engineering applications. Such phenomena occur almost inevitably in any transonic or supersonic flow and the subject has given rise to an important research effort since the advent of high speed fluid mechanics, more than forty years ago. However, with the coming of age of modern computers and the development of new sophisticated measurement techniques, considerable progress has been made in the field over the past fifteen years. The aim of the symposium was to provide an updated status of the research effort devoted to shear layer/shock-wave interactions and to present the most significant results obtained recently.

Book Introduction to Transonic Aerodynamics

Download or read book Introduction to Transonic Aerodynamics written by Roelof Vos and published by Springer. This book was released on 2015-03-04 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written to teach students the nature of transonic flow and its mathematical foundation, this book offers a much-needed introduction to transonic aerodynamics. The authors present a quantitative and qualitative assessment of subsonic, supersonic and transonic flow around bodies in two and three dimensions. The book reviews the governing equations and explores their applications and limitations as employed in modeling and computational fluid dynamics. Some concepts, such as shock and expansion theory, are examined from a numerical perspective. Others, including shock-boundary-layer interaction, are discussed from a qualitative point of view. The book includes 60 examples and more than 200 practice problems. The authors also offer analytical methods such as Method of Characteristics (MOC) that allow readers to practice with the subject matter. The result is a wealth of insight into transonic flow phenomena and their impact on aircraft design, including compressibility effects, shock and expansion waves, shock-boundary-layer interaction and aeroelasticity.

Book Reynolds Number Effects on the Shock Wave Turbulent Boundary Layer Interaction at Transonic Speeds

Download or read book Reynolds Number Effects on the Shock Wave Turbulent Boundary Layer Interaction at Transonic Speeds written by R. J. Vidal and published by . This book was released on 1973 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Ludwieg tube experiment is described in which the pertinent features of the shock wave-boundary layer interaction on an airfoil are simulated with a two-dimensional flat plate in a supersonic nozzle. The nozzle is modified to impress an airfoil pressure distribution on the flat plate that is typical of a cruising flight condition. A normal shock wave is positioned at a fixed location on the plate, and measurements are made in the vicinity of the shock wave-boundary layer interaction zone.

Book Some Fundamental Aspects of Shock Wave   Turbulent Boundary Interactions in Transonic Flow

Download or read book Some Fundamental Aspects of Shock Wave Turbulent Boundary Interactions in Transonic Flow written by G. R. Inger and published by . This book was released on 1981 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transonic normal shock - turbulent boundary layer interactions can significantly influence not only the local viscous flow but also the downstream behavior of the boundary layer on aerodynamic bodies. It is therefore important that fundamentally-based analytical tools be developed for describing and scaling these interaction effects. This paper examines recent progress toward this goal, with emphasis on two aspects. (1) A basic non-asymptotic triple-deck theory of non-separating two-dimensional interactions that is applicable over a wide range of practical Reynolds numbers and boundary layer profile shapes. (2) Its applicable as a local 'interactive module' in the global transonic flow field analysis of wings, including detailed comparisons with experimental data. Also discussed is the adaptability of this theory to treat interactions involving non-adiabatic wall conditions, including the prediction of incipient separation.

Book Interaction of a Turbulent Boundary Layer with a Normal Shock Wave Followed by an Adverse Pressure Gradient

Download or read book Interaction of a Turbulent Boundary Layer with a Normal Shock Wave Followed by an Adverse Pressure Gradient written by W. H. Schofield and published by . This book was released on 1983 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was made of the development of a turbulent boundary layer after an interaction with a normal shock wave (strong enough to cause a local separation) in a strong adverse pressure gradient. This type of flow, which occurs in air breathing engine components (e.g. supersonic intakes, transonic compressor stages and supersonic diffusers), is poorly understood and cannot be satisfactorily predicted. The measurements, made in a closed duct, extended well downstream of the shock wave interaction. Detailed results for the flow are presented and used to support two major conclusions. It is shown that the post shock adverse pressure gradient has a large effect on boundary layer development through the interaction and downstream of it. Consequently existing results for interactions without a post shock pressure gradient should not be used as a model for practical flows which typically have strong pressure gradients applied downstream of the shock wave. The second conclusions was that the shock wave in a rectangular duct produced a pronounced stabilising effect on the downstream flow. Surface flow visualization suggests that this stabilization is achieved by streamwise vortices shed into the flow from the separated region formed by the shock wave. Implications of this result to nominally two-dimensional flow situations and to flows with weak interactions without local separations are discussed.

Book A Study of Normal Shock Wave Turbulent Boundary Layer Interactions at Mach Numbers of 1 3  1 4 and 1 5

Download or read book A Study of Normal Shock Wave Turbulent Boundary Layer Interactions at Mach Numbers of 1 3 1 4 and 1 5 written by W. G. Sawyer and published by . This book was released on 1982 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the results of a study of seven flows involving the interaction between a normal shock wave and a two-dimensional turbulent boundary layer. The measurements were made at free-stream Mach numbers of 1.3, 1.4 and 1.5 and at Reynolds numbers based on an effective streamwise run of 10 to 30-million. The results were obtained from comprehensive traverses with both pilot and static probes. Standard boundary-layer integral parameters based on wall and measured static pressures are presented, together with velocity profiles and the Mach number distribution over the interaction region. An investigation has been made of the 'law of the wall' and the 'law of the wake' under the influence of strong normal pressure gradients.
