Download or read book Mathematical and Computational Methods for Compressible Flow written by Miloslav Feistauer and published by Oxford University Press, USA. This book was released on 2003 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with mathematical and numerical methods for compressible flow. It aims to provide the reader with a sufficiently detailed and extensive, mathematically precise, but comprehensible guide, through a wide spectrum of mathematical and computational methods used in Computational Fluid Dynamics (CFD) for the numerical simulation of compressible flow. Up-to-date techniques applied in the numerical solution of inviscid as well as viscous compressible flow on unstructured meshes are explained, thus allowing the simulation of complex three-dimensional technically relevant problems. Among some of the methods addressed are finite volume methods using approximate Riemann solvers, finite element techniques, such as the streamline diffusion and the discontinuous Galerkin methods, and combined finite volume - finite element schemes. The book gives a complex insight into the numerics of compressible flow, covering the development of numerical schemes and their theoretical mathematical analysis, their verification on test problems and use in solving practical engineering problems. The book will be helpful to specialists coming into contact with CFD - pure and applied mathematicians, aerodynamists, engineers, physicists and natural scientists. It will also be suitable for advanced undergraduate, graduate and postgraduate students of mathematics and technical sciences.

This book was released on 1965 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unified performance prediction method was developed for class A diffusers. Class A diffusers have specified flow and geometry restrictions. The prediction method is a system of linear, first order differential equations. These equations embody the momentum equation, continuity equation, and two empirical correlation equations. In addition to the prediction method, two parameters were developed to characterize inlet conditions and separation respectively.

Download or read book Computational Analysis of Unsteady Circumferential and Radial Distortion in Subsonic Diffusers written by John I. Erdos and published by . This book was released on 1973 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two computational models of the unsteady flow in the subsonic diffuser section of an axisymmetric, external compression, supersonic inlet are described. The first pertains to the inviscid flow on a cylindrical stream surface through the diffuser, from the terminal shock to a discharge station representing the engine face. The equations of motion for a compressible gas are solved numerically by a second order finite difference technique. Several numerical examples are carried out to illustrate the capabilities of the computational model; the results are discussed and interpreted in relation to the problem of experimental simulation of circumferential distortion. The second computational model pertains to the axisymmetric flow in meridional planes through the subsonic diffuser. (Modified author abstract).

Download or read book An Introduction to Compressible Flows with Applications written by José Pontes and published by Springer Nature. This book was released on 2019-12-02 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a concise and practical survey of the principles governing compressible flows, along with selected applications. It starts with derivation of the time-dependent, three-dimensional equation of compressible potential flows, and a study of weak waves, including evaluation of the sound speed in gases. The following chapter addresses quasi-one-dimensional flows, the study of normal shock waves, and flow in ducts with constant cross section subjected to friction and/or heat transfer. It also investigates the effects of friction and heat transfer in ducts with variable cross section. The chapter ends by pointing to the analogy between one-dimensional compressible flows and open channel hydraulics. Further, the book discusses supersonic flows, including the study of oblique shock waves, and supersonic flows over corners and wedges. It also examines Riemann problems, numerical resolution of the wave equation, and of nonlinear hyperbolic problems, including propagation of strong waves. A subsequent chapter focuses on the small perturbation theory of subsonic, transonic and supersonic flows around slender bodies aligned or almost aligned to the uniform inflow. In particular, it explores subsonic and supersonic flows over a wavy wall. Lastly, an appendix with a short derivation of the Fluid Mechanics basic equations is included. The final chapter addresses the problem of transonic flows where both subsonic and supersonic are present. Lastly, an appendix with a short derivation of the Fluid Mechanics basic equations is included. Illustrated with several practical examples, this book is a valuable tool to understand the most fundamental mathematical principles of compressible flows. Graduate Mathematics, Physics and Engineering students as well as researchers with an interest in the aerospace sciences benefit from this work.

Available in PDF, EPUB and Kindle. Book excerpt: A marching procedure for solving the finite difference equations describing inviscid, subsonic, compressible flow in an axisymmetric duct is described. The concept of artificial viscosity is introduced and special provisions for maintaining continuity are included. The method predicts the pressure and velocity distributions at any axial station in the duct. A computer program and several sample results are also presented and discussed. (Author).
