Available in PDF, EPUB and Kindle. Book excerpt: Mixing of two streams of compressible fluid having arbitrary properties at the start of mixing results in one of two possible states upon conclusion of the mixing process. These two final states can be differentiated by the fact that the Mach Number of the fully mixed flows are related in the same manner as are the Mach Numbers across a normal shock wave. One of these states is always representative of a subsonic flow and the other a supersonic flow. Since both solutions represent flows which satisfy the laws of mass flow and energy conservation and the momentum theorum in a channel of uniform cross-section, the physical possibility of achieving these end states must be corroborated by examination of the process in terms of the Second Law of Thermodynamics. Therefore the total entropy change of the flows from the initial to the final state have been determined. It is shown that both solutions correspond to flows which have a positive entropy change in certain ranges of the initial conditions while in other ranges the solution corresponding to a supersonic end state may violate the Second Law of Thermodynamics. Applications of these solutions to the flow through an ejector provide a means for design optimization which results in high thrust augmentating capability at any given flight speed. (Author).

Download or read book An Introduction to Compressible Flows with Applications written by José Pontes and published by Springer. This book was released on 2019-12-16 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.
