Available in PDF, EPUB and Kindle. Book excerpt: Existing theoretical analyses and experimental results of the stagnation region in hypersonic flow at low Reynolds number are discussed. The approach based on the thin-shock-layer approxi mation is extended to study flow fields beyond the stagnation region as well as in the shock transition zone. The basic flow model consists of two adjoining thin layers: a shock-transition zone and a shock layer. The system of partial differential equations governing the high-density shock layer reduces to the parabolic type. The system governing the shock-transition zone reduces to ordinary differential equations similar to those of the one-dimensional shock wave. They give rise to a set of conservation relations across the shock, which account for the transport processes immediately behind the shock but do not involve details of shock-wave structure. With the modified Rankine-Hugoniot relations, the flow field in shock layer can be determined independ ently of the shock-transition zone. An essential feature of this formulation is that, when applied in conjunction with nonslip surface conditions, it always yields the appropriate surface heat transfer rate and skin friction (for unit accommo dation coefficients) in the free-molecule limit.

Download or read book Nonequilibrium Blunt Body Flow of Air at Low Reynolds Number written by Arnold J. Galloway and published by . This book was released on 1972 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report treats the nonequilibrium air flow around blunt bodies at high altitudes and reentry conditions. The inverse method is employed, and a reduced form of the Navier-Stokes equations is solved by finite difference techniques. Solutions are obtained for the flow around bodies which generate spherical, parabolic, and hyperbolic shock shapes. Body shapes closely resembling spherically blunted cones are obtained. The present solutions are compared with a very limited data base and other calculations. The results are shown to agree reasonably well with the data and the independent calculations.

Download or read book Hypersonic Flow Research written by F.R. Riddell and published by Elsevier. This book was released on 2012-12-02 with total page 769 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress in Astronautics and Rocketry, Volume 7: Hypersonic Flow Research compiles papers presented at a conference on hypersonics held at the Massachusetts Institute of Technology in August 1961. This book discusses the low Reynolds number effects, chemical kinetics effects, inviscid flow calculations, and experimental techniques relating to the problems in acquiring an understanding of hypersonic flow. The structure and composition of hypersonic wakes with attendant complex chemical kinetic effects is only briefly mentioned. This text consists of five parts. Parts A to C comprise of theoretical papers on the problems of calculating flow fields at hypersonic speeds. The experimental techniques that are of immediate practical interest in view of the difficulty of flight testing are discussed in Parts D and E. This publication is beneficial to engineers involved in advanced design problems.

Download or read book Hypersonic Flow Theory written by Wallace Hayes and published by Elsevier. This book was released on 2012-12-02 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hypersonic Flow Theory presents the fundamentals of fluid mechanics, focusing on the hypersonic flow theory and approaches in theoretical aerodynamics. This book discusses the assumptions underlying hypersonic flow theory, unified supersonic-hypersonic similitude, two-dimensional and axisymmetric bodies, and circular cylinder. The constant-streamtube-area approximation, streamtube-continuity methods, and tangent-wedge and tangent-cone are also deliberated. This text likewise covers the similar laminar boundary layer solutions, bluntness induced interactions on slender bodies, and free molecule transfer theory. The dynamics of hypersonic flight or hypersonic wing theory, magnetohydrodynamic theory, or any developments involving treatment of the Boltzmann equation are not included. This publication is intended for hypersonic aerodynamicists, students, and researchers conducting work on the hypersonic flow phenomena.

Download or read book Hypersonic Flows for Reentry Problems written by Jean-Antoine Desideri and published by Springer. This book was released on 1992-01-17 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the most challenging problems of modern engineering is undoubtedly the prediction of hypersonic flows around space vehicles in reentry conditions. Indeed, the difficulties are numerous: first of all, these flows are very difficult to model, since very complex physical and chemical phenomena take place during the reentry phase; secondly, temperature, velocity and enthalpy are very high and densities are very low, making the reentry process very difficult to reproduce in ground-based experiments. The past three decades have seen important efforts in computational fluid dynam ics relying on the use of supercomputers to simulate these very complicated flows. The numerical simulation based on imperfect models and methods which were es sentially designed for transonic and supersonic flows has still a long way to go in order to be able to predict these hypersonic reentry flows very accurately. This situation has motivated very strong international cooperative efforts with, as the most visible consequences, the EuropelUnited States Short Courses on Hy personics, which were held in Paris, in 1987 [1,2], Colorado Springs in 1989 [3], and Aachen in 1990 [3]. The workshop on Hypersonics whose results are presented and analysed in these volumes is also a direct consequence of this international cooperation. This scien tific event was an initiative of P. Perrier, Head of the Theoretical Aerodynamics Department of DASSAULT AVIATION, who played a key role in the identification of the critical problems and the realisation of experiments, within the Hermes R&D program framework.
