Book Synopsis Real Gas Flows with High Velocities by : Vladimir V. Lunev
Download or read book Real Gas Flows with High Velocities written by Vladimir V. Lunev and published by CRC Press. This book was released on 2009-06-03 with total page 751 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite generations of change and recent, rapid developments in gas dynamics and hypersonic theory, relevant literature has yet to catch up, so those in the field are generally forced to rely on dated monographs to make educated decisions that reflect present-day science. Written by preeminent Russian aerospace researcher Vladimir V. Lunev, Real Gas Flows with High Velocities reflects the most current concepts of high-velocity gas dynamics. For those in aviation and aerospace, this is a vital methodical revitalization and reassessment of real gas flows with regard to the physical and gasdynamic effects related to high-velocity flight, and, in particular, the entry of bodies into the atmosphere of Earth and other planets. Much more than just a manual on gas physics, this book: Analyzes fundamental challenges associated with super- and subsonic flight Describes the physical properties of gas mixtures and their associated high-temperature processes from the phenomenological standpoint Explores use of computational mathematics and equipment to simplify previously unsolvable problems of inviscid and viscous gas dynamics Explains why numerical methods remain inferior to analytical methods for creating a conceptual understanding of gas dynamic and other physical problems Avoiding older, cumbersome approximate methods, this reference outlines the general patterns and features of typical flows and how real gas affects them. Referencing simple, analytically treatable examples, similarity laws, and asymptotic analysis, the author omits superfluous explanation of reasoning. This valuable reference summarizes general theory of super- and subsonic flow and uses practical problems to develop a solid understanding of modern real-gas flows and high-velocity gas dynamics.

Book Synopsis Introduction to Reactive Gas Dynamics by : Raymond Brun
Download or read book Introduction to Reactive Gas Dynamics written by Raymond Brun and published by OUP Oxford. This book was released on 2009-02-26 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: In high energy gas flows, at high velocities and high temperatures, physical and chemical processes such as molecular vibrational excitation, dissociation, ionisation or various reactions take place and deeply influence the structure of the flows. The characteristic times of these processes have the same order of magnitude as aerodynamic characteristic times, so that these reactive media are generally in thermodynamic and chemical non-equilibrium. This book presents a general introductory study of these media. In the first part their fundamental statistical aspects are described, starting from their discrete structure and taking into account the interactions between elementary particles: transport phenomena, relaxation and kinetics as well as their coupling are analysed and illustrated by many examples. The second part deals with the macroscopic re-entry bodies. Finally, the experimental aspects of these flows, their simulations in shock tubes and shock tunnels are described, as well as their application, particularly in the aerospatial domain. This book is intended for students that have acquired a basic knowledge in thermodynamics, statistical physics and fluid mechanics. It will also be of interest to engineers in research and industry, in particular in the aerospace industry, and more generally to all researchers trying to simulate and calculate complex reactive flows.

Book Synopsis Theoretical Analysis of Stationary Potential Flows and Boundary Layers at High Speed by : Klaus Oswatitsch
Download or read book Theoretical Analysis of Stationary Potential Flows and Boundary Layers at High Speed written by Klaus Oswatitsch and published by . This book was released on 1948 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: The present report consists of two parts. The first part deals with the two-dimensional stationary flow in the presence of local supersonic zones. A numerical method of integration of the equation of gas dynamics is developed. Proceeding from solutions at great distance from the body the flow pattern is calculated step by step. Accordingly the related body form is obtained at the end of the calculation. The second part treats the relationship between the displacement thickness of laminar and turbulent boundary layers and the pressure distribution at high speeds. The stability of the boundary layer is investigated, resulting in basic differences in the behavior of subsonic and supersonic flows. Lastly, the decisive importance of the boundary layer for the pressure distribution, particularly for thin profiles, is demonstrated.
Book Synopsis High-Resolution Methods for Incompressible and Low-Speed Flows by : D. Drikakis

This book was released on 2005-08-02 with total page 623 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of incompressible ?ows is vital to many areas of science and te- nology. This includes most of the ?uid dynamics that one ?nds in everyday life from the ?ow of air in a room to most weather phenomena. Inundertakingthesimulationofincompressible?uid?ows,oneoftentakes many issues for granted. As these ?ows become more realistic, the problems encountered become more vexing from a computational point-of-view. These range from the benign to the profound. At once, one must contend with the basic character of incompressible ?ows where sound waves have been analytically removed from the ?ow. As a consequence vortical ?ows have been analytically “preconditioned,” but the ?ow has a certain non-physical character (sound waves of in?nite velocity). At low speeds the ?ow will be deterministic and ordered, i.e., laminar. Laminar ?ows are governed by a balance between the inertial and viscous forces in the ?ow that provides the stability. Flows are often characterized by a dimensionless number known as the Reynolds number, which is the ratio of inertial to viscous forces in a ?ow. Laminar ?ows correspond to smaller Reynolds numbers. Even though laminar ?ows are organized in an orderly manner, the ?ows may exhibit instabilities and bifurcation phenomena which may eventually lead to transition and turbulence. Numerical modelling of suchphenomenarequireshighaccuracyandmostimportantlytogaingreater insight into the relationship of the numerical methods with the ?ow physics.
Book Synopsis Perturbations in High-velocity Gas Flow by :
Download or read book Perturbations in High-velocity Gas Flow written by and published by . This book was released on 1989 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: High velocity explosive products or other low-density gases are often used to accelerate metal plates to high velocities. Perturbations in otherwise uniform flow configurations are sometimes sufficient to cause interactions that can rapidly destroy the integrity of the plates. In this study perturbations were introduced in uniform gas flows of detonated HE products and strongly shocked polyethylene, CH2. The primary diagnostics were smear-camera records obtained when these gases impinged on layers of plexiglas separated by small argon-filled gaps. These records show shock-arrival times at various levels and thus determine not only the size of the perturbation but also its strength. Perturbations in HE gases running into H2 and in CH2 into H2 have been studied. Two-dimensional hydrodynamic calculations are in excellent agreement with the experiments, and enable one to study details of the flow not possible from experimental results. 1 ref., 5 figs.
Book Synopsis Relaxation Phenomena at a High Speed Gas Flow by : M. A. Yelyashevich
Download or read book Relaxation Phenomena at a High Speed Gas Flow written by M. A. Yelyashevich and published by . This book was released on 1963 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: When solving the problem of gas dynamics it is frequently assumed that outer effects on the fl;0 hange the state of the gas quite slowly, so that in each point sets in an equilibrium between various degrees of freedom of gas molecules. In fact the process of setting in an equilibrium requires a finite time, and it can be expected, that at sufficiently rapidly changing outer influences against the flow no equilibrium will be reached. The problem in this case becomes quite complicated because in the system of gas dynamics equations are added kinetic equations, describing the change in state of inert degrees of freedom of gas molecules. A simple approxi mate calculation method is offered to calculate the nonequilibrium of the flow, based on the fact, that in all instances of practical interest the flow appears to be locally close either to equilibrium, or to the frozen, wherby the zones of almost equilibrium and almost frozen flow are separated by a sufficiently lucid boundary.

Book Synopsis On the Assumption of Specific-heat Ratio Near One in the Theory of High-energy Gas Flows by : Franklin Kingston Moore
Download or read book On the Assumption of Specific-heat Ratio Near One in the Theory of High-energy Gas Flows written by Franklin Kingston Moore and published by . This book was released on 1965 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The assumption that the ratio of specific heats is near one is of dominant importance in real-gas flow theory for hypersonic shock layers, scaling for dissociating flows, local similarity of the hypersonic boundary layer, and the theory of weak disturbances of a highly excited gas. Certain of these problems are briefly reviewed, chiefly to explain the advantages conferred by this assumption which, though poor a priori, has the power to unify diverse problems, often with surprising accuracy. Special attention is paid to the real-gas theory of sound waves, showing how a reduction of order is achieved for any process of energy release coupled with a state variable. Dispersal by chemical relaxation and by radiative transfer are described as examples. (Author).

Book Synopsis Real-gas Correction Factors for Hypersonic Flow Parameters in Helium by : Wayne Douglas Erickson
Download or read book Real-gas Correction Factors for Hypersonic Flow Parameters in Helium written by Wayne Douglas Erickson and published by . This book was released on 1960 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: The real-gas hypersonic flow parameters for helium have been calculated for stagnation temperatures from 0 F to 600 F and stagnation pressures up to 6,000 pounds per square inch absolute. The results of these calculations are presented in the form of simple correction factors which must be applied to the tabulated ideal-gas parameters. It has been shown that the deviations from the ideal-gas law which exist at high pressures may cause a corresponding significant error in the hypersonic flow parameters when calculated as an ideal gas. For example the ratio of the free-stream static to stagnation pressure as calculated from the thermodynamic properties of helium for a stagnation temperature of 80 F and pressure of 4,000 pounds per square inch absolute was found to be approximately 13 percent greater than that determined from the ideal-gas tabulation with a specific heat ratio of 5/3.
