This book was released on 1956 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because the chemical reaction rates needed to predict the dependence of degree of dissociation on distance behind the shock are not known, order-of-magnitude estimates of their values have been used in a numerical example, the purpose of which is to illustrate the use of reaction-rate equations to predict relaxation time and distance behind the shock front.
Book Synopsis A Technique for Determining Relaxation Times by Free-Flight Tests of Low-Fineness-Ratio Cones; With Experimental Results for Air at Equilibrium Temperatures Up to 3440 K by : Jack D. Stephenson
Download or read book A Technique for Determining Relaxation Times by Free-Flight Tests of Low-Fineness-Ratio Cones; With Experimental Results for Air at Equilibrium Temperatures Up to 3440 K written by Jack D. Stephenson and published by . This book was released on 1960 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a technique which combines theory and experiments for determining relaxation times in gases. The technique is based on the measurement of shapes of the bow shock waves of low-fineness-ratio cones fired from high-velocity guns. The theory presented in the report provides a means by which shadowgraph data showing the bow waves can be analyzed so as to furnish effective relaxation times. Relaxation times in air were obtained by this technique and the results have been compared with values estimated from shock tube measurements in pure oxygen and nitrogen. The tests were made at velocities ranging from 4600 to 12,000 feet per second corresponding to equilibrium temperatures from 35900 R (19900 K) to 6200 R (34400 K), under which conditions, at all but the highest temperatures, the effective relaxation times were determined primarily by the relaxation time for oxygen and nitrogen vibrations.

Book Synopsis Measurements of the Dissociation Rate of Molecular Oxygen by : Charles J. Schexnayder
Download or read book Measurements of the Dissociation Rate of Molecular Oxygen written by Charles J. Schexnayder and published by . This book was released on 1961 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ability of molecular oxygen to absorb light in the Schumann-Runge ultraviolet region of the spectrum has been used to follow the change in concentration of molecular oxygen as a function of time behind shock waves in oxygen and in a mixture of 10-percent oxygen in argon. Analysis of the records obtained yielded values for the dissociation rate of oxygen as a function of temperature over the range 4,000° to 10,000°K. The highest previously reported experimental results in the literature were at 7,500°K.

Book Synopsis Theoretical Studies of Supersonic Two-dimensional and Axisymmetric Nonequilibrium Flow, Including Calculations of Flow Through a Nozzle by : James Joe Der
Download or read book Theoretical Studies of Supersonic Two-dimensional and Axisymmetric Nonequilibrium Flow, Including Calculations of Flow Through a Nozzle written by James Joe Der and published by . This book was released on 1963 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical and vibrational nonequilibrium phenomena in steady inviscid flow fields are studied by the analysis of flow past curved boundaries. Possible alternative choices of the state variables to be used are considered. General features of the nonequilibrium flow are studied by examination of the mathematical properties of the nonlinear flow equations. An axisymmetric nonequilibrium flow of air through a supersonic nozzle is analyzed by means of numerical computations. The coupling effects between nonuniformity (across a nozzle section) and nonequilibrium, not taken into account in the quasi-one-dimensional flow approximation, are revealed by the present analysis.

Download or read book Advances in Aeronautical Sciences written by Th. Von Kármán and published by Elsevier. This book was released on 2014-05-15 with total page 621 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advances in Aeronautical Sciences, Volume 3 contains the proceedings of the Second International Congress in the Aeronautical Sciences held in Zurich, Switzerland, on September 12-16, 1960. The papers explore advances in aeronautical sciences and cover topics ranging from the role of entropy in the aerospace sciences to the theory of hypersonic flow over blunt-nosed slender bodies. The effect of boundary layer transition at the leading edge of thin wings on general nose separation is also discussed, along with the aerodynamics of aircraft shapes for flight at supersonic speeds. This book is comprised of 28 chapters and begins with a review of the importance of entropy in the aerospace sciences, citing the work of Nicolaus Sadi Carnot and Rudolf Clausius as well as enthalpy and free enthalpy. The link between entropy and molecular theory is also described before turning to the physics of jet streams and the aerodynamics of jet flaps. Other chapters consider a wide range of problems both of theoretical and practical importance, including the flow around a circular cylinder; the theory of boundary layer; the physics of transition from laminar to turbulent flow; and the theory and experimental knowledge of transonic, supersonic, and hypersonic flows. Due attention is given to the re-entry of missiles and space vehicles into the atmosphere; problems of trajectories; guidance of space vehicles; and power generation in space. The economic and technical aspects of air transportation are also highlighted. This volume will be of interest to scientists and engineers in aeronautics and astronautics.
