Available in PDF, EPUB and Kindle. Book excerpt: With the always advancing aviation and space industries, supersonic and hypersonic flows are continually becoming more important to model and understand. Inviscid, compressible fluid mechanics are described by systems of hyperbolic partial differential equations, which are used in this thesis to model various supersonic and hypersonic flows. These flows include those through a converging-diverging nozzle, over a two dimensional wedge, over a cone, and over airfoils. Various flow phenomena such as normal, bow, oblique, and fishtail shocks are correctly modeled and shown. Through analysis of the results, it is found that each of the models in this paper demonstrate the correct qualitative flow characteristics for each set of boundary conditions. Accurate data for normal and attached shocks, including the shock position, shock angle, and post-shock flow conditions, as well as accurate expansion fan pressures are found and verified with various publications, all while using very simple numerical methods which are easy to implement and program.

This book was released on 2013-03-09 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is concerned with mathematical modelling of supersonic and hyper sonic flows about bodies. Permanent interest in this topic is stimulated, first of all, by aviation and aerospace engineering. The designing of aircraft and space vehicles requires a more precise prediction of the aerodynamic and heat transfer characteristics. Together with broadening of the flight condition range, this makes it necessary to take into account a number of gas dynamic and physical effects caused by rarefaction, viscous-inviscid interaction, separation, various physical and chemical processes induced by gas heating in the intensive bow shock wave. The flow field around a body moving at supersonic speed can be divided into three parts, namely, shock layer, near wake including base flow, and far wake. The shock layer flow is bounded by the bow shock wave and the front and lat eral parts of the body surface. A conventional approach to calculation of shock layer flows consists in a successive solution of the inviscid gas and boundary layer equations. When the afore-mentioned effects become important, implementation of these models meets difficulties or even becomes impossible. In this case, one has to use a more general approach based on the viscous shock layer concept.

Download or read book Solution of Some 3-D Viscous and Inviscid Supersonic Flow Problems by Finite-Volume Space-Marching Schemes written by H. Rieger and published by . This book was released on 1987 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: For prediction of steady supersonic flow fields two numerical methods for solution of the three-dimensional Euler-and parabolized Navier-Stokes (PNS- ) equations are considered. Both are based on a Finite-Volume discretisation (FVD) of the governing conservation laws and because of the special properties of steady supersonic flows cost-effective space-marching integration techniques can be applied. Both methods are described and results for inviscid and viscous flows are presented. In view of the upcoming European Space Transportation activities the simulation of hypersonic flows past complex blunted lifting vehicles requires also efficient methods for solution of the full, not-reduced Navier-Stokes equations. These are needed to provide solutions for super- and hypersonic flow fields with large subsonic regions and also to get accurate initial conditions for the space marching codes developed. A relaxation procedure for the steady form of the not-reduced Navier-Stokes and the Euler equations is described and some first results are presented.

Book Synopsis Hypersonic Flow Theory by : Wallace Hayes
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.

Available in PDF, EPUB and Kindle. Book excerpt: These three volumes entitled Advances in Hypersonics contain the Proceedings of the Second and Third Joint US/Europe Short Course in Hypersonics which took place in Colorado Springs and Aachen. The Second Course was organized at the US Air Force Academy, USA in January 1989 and the Third Course at Aachen, Germany in October 1990. The main idea of these Courses was to present to chemists, com puter scientists, engineers, experimentalists, mathematicians, and physicists state of the art lectures in scientific and technical dis ciplines including mathematical modeling, computational methods, and experimental measurements necessary to define the aerothermo dynamic environments for space vehicles such as the US Orbiter or the European Hermes flying at hypersonic speeds. The subjects can be grouped into the following areas: Phys ical environments, configuration requirements, propulsion systems (including airbreathing systems), experimental methods for external and internal flow, theoretical and numerical methods. Since hyper sonic flight requires highly integrated systems, the Short Courses not only aimed to give in-depth analysis of hypersonic research and technology but also tried to broaden the view of attendees to give them the ability to understand the complex problem of hypersonic flight. Most of the participants in the Short Courses prepared a docu ment based on their presentation for reproduction in the three vol umes. Some authors spent considerable time and energy going well beyond their oral presentation to provide a quality assessment of the state of the art in their area of expertise as of 1989 and 1991.

Book Synopsis Hypersonic Flows for Reentry Problems by : Jean-Antoine Desideri
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.

Book Synopsis Turbulence in Hypersonic Flow by : Gustave J. Hokenson
Download or read book Turbulence in Hypersonic Flow written by Gustave J. Hokenson and published by . This book was released on 1987 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical simulations of hypersonic shear flow, utilizing the full-time-dependent compressible flow Navier-Stokes equations, have been carried out to demonstrate the feasibility of exposing, computationally, the essential structure/physic of turbulent fluctuations in high speed flow. The geometry employed is one of interest to the U.S. Air Force in various applications, namely a right circular cylinder whose axis is aligned with the on-coming flow and around which the cylinder could be rotated. By simulating the flow along a cylinder of the infinite axial extent, an exceptionally quiet flow was established. Due to limitations of computational time, it was necessary to excite artificially this flowfield with periodic suction and blowing located well upstream of the observation plane. As a result, fluctuations in the flowfield entropy, vorticity and pressure were observed which revealed a distinct Mach number dependence. At hypersonic Mach numbers, the fluctuating entropy defined a second boundary layer edge, well beyond that of the vorticity but not propagating deep into the inviscid, flow, as was observed in both transonic and supersonic regimes.

Book Synopsis Numerical Simulation of Compressible Euler Flows by : Alain Dervieux
Download or read book Numerical Simulation of Compressible Euler Flows written by Alain Dervieux and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: The numerical simulation of the Euler equations of Fluid Dynamics has been these past few years a challenging problem both for research scientists and aerospace engineers. The increasing interest of more realistic models such as the Euler equations originates in Aerodynamics and also Aerothermics where aerospace applications such as military aircrafts and also space vehicles require accurate and efficient Euler solvers (which can be extended to more complicated modelisations including non-equilibrium chemistry) for su personic and hypersonic flows at high angles of attack and Mach number regimes involving strong shocks and vorticity. This book contains the proceedings of the GAMM Workshop on the Numerical Simu lation of Compressible Euler Flows. that W:LS held at INRIA, Rocquencourt (France), on June 10-13, 1986. The purpose of this event was to compare in terms of accuracy and efficiency several codes for solving compressible inviscid, mainly steady, Euler flows. This workshop was a sequel of the GAMM workshop held in 1979 in Stockholm; this time, though, because of the present strong activity in numerical methods for the Euler equat.ions, the full-potential approach was not included. Since 1979, other Eulpr workshops have been organised, sev eral of them focussed on airfoil calculations; however, many recently derived methods were not presented at these workshops, because, among other reasons, the methods were not far enough developed, or had not been applied to flow problems of sufficient complexity. In fact, the 1986 GAMM workshop scored very high as regards to the novelty of methods.
