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 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 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 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 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 An Experimental and Analytic Investigation of a Transonic Shock wave boundary layer Interaction

Download or read book An Experimental and Analytic Investigation of a Transonic Shock wave boundary layer Interaction written by M. C. Alstatatt and published by . This book was released on 1977 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two wind tunnel tests were conducted in a flow exhibiting a shock-wave/boundary-layer interaction of the type occurring on airfoils at transonic velocities. Boundary-layer pressure distributions were measured with pitot and static probes. Velocities in the free stream and in the boundary layer were obtained with a laser velocimeter (LV) system, and a data reduction program for the LV results was developed. Measurements from the pressure probes and from the LV system are compared with each other and with theoretical computations. It was found that the analytic models for boundary-layer velocity profile and Reynolds stress agree well with experimental measurements. (Author).

Book On Transonic Shock Wave Boundary Layer Interaction Flow Patterns

Download or read book On Transonic Shock Wave Boundary Layer Interaction Flow Patterns written by G. R. Inger and published by . This book was released on 1974 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A review is made of the existing knowledge about the interaction of impinging shock waves with laminar or turbulent boundary layers, to emphasize and illustrate that the relative degree of inviscid-dominated (solid wall-like) reflection behavior versus viscous-dominated (free surface-like) reflection is a major feature determining the disturbance flow pattern. This idea is then used to appraise existing transonic normal shock-boundary layer interaction experiments and establish an ordered relationship between them. As a result, it is shown that far from being unusual, a post-shock pocket of supersonic flow ("supersonic tongue") is in fact a common feature of all such interaction patterns, although its scale can change drastically with incident shock strength, Reynolds number and downstream conditions.
