Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this study were to correlate jet mixing data to establish mixing model coefficients and to produce empirical correlations of jet core length and centerline decay rate. A literature review containing 312 jet mixing experiments is reported. Turbulent jet mixing coefficients for 249 experiments are correlated, resulting in predictions of core length and decay rate for all experiments with an error of about 20-25%. Empirical correlations of core length and decay rate are also presented which give direct engineering estimates of these parameters with an error about 20-25% without the use of a jet mixing model.

This book was released on 2013-03-09 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by TPRC at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemina tion phases of the activity was transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we have concluded that it will be in the interest of all concerned if the printing and distribution of the volume were handled by a well-known publishing house to assure improved service and better communication. Hence, effective with this Volume 18, Masters Theses in the Pure and Applied Sciences will be disseminated on a worldwide basis by Plenum Publishing Corporation of New York. All back issues can also be ordered from Plenum. As we embark on this new partnership with Plenum, we also initiate a new venture in that this important annual reference work now covers Canadian universities as well as those in the United States. We are sure that this broader base will greatly enhance the value of these volumes.

Available in PDF, EPUB and Kindle. Book excerpt: The turbulent mixing of confined axisymmetric incompressible jets was studied, using the turbulent boundary layer equations in terms of transformed von Mises variables, with semi-empirical formulations of the turbulent transport coefficients. The solution was obtained by the method of finite differences. Analytical predictions of the jet mixing flow fields were obtained for several configurations, covering a resonably wide range of values of the problem parameters. A turbulent mixing model which satisfactorily predicts mean flow profiles for a reasonably broad spectrum of flow conditions has been formulated.

This book was released on 1965 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent attempts to predict the heat transfer from a high enthalpy, compressible free jet impinging upon surfaces in its path have suffered from a complete lack of knowledge concerning the behavior of turbulent jets of dissociated gases. Although it had been assumed that high enthalpy gas streams would exhibit the characteristics of cold jets, which have been subjected to extensive study, there had been no experimental evidence to support this contention. A research program was conducted to determine radial and axial variations in fluid properties, i.e., velocity, density, enthalpy, etc., in compressible free jets of dissociated gases produced by electric-arc plasma generators. Experimental investigations were confined to the near flowfield of the jets, since 90 percent of change in jet fluid properties, from their initial values at the arc nozzle-exit plane to the properties of the ambient fluid, was accomplished within 40 nozzle radii from the jet origin. Heat-transfer rates from these jets, when impinging upon a flat surface perpendicular to the jet axis, were determined experimentally. Correlation of this data could then be accomplished by means of a relationship similar to those for stagnation-point heat transfer to blunt bodies in a uniform stream when local jet properties were employed.

Available in PDF, EPUB and Kindle. Book excerpt: The two different sets of equations derived by Tollmein and Goertler for the two-dimensional, compressible, free jet mixing layer using the similarity assumption have been programmed for the IBM 7044, and solutions to a wide variety of problems carried out. These solutions demonstrate the validity and accuracy of the method, illustrate the effects of changes in Prandtl number and other parameters, compare results of the Tollmein and Goertler methods, and provide analytical curves used for evaluating the spreading parameter. A new correlation for spreading parameter is presented. A first-order correction for afterburning, assuming complete stoichiometric combustion at a flame front, allows the method to be applied to fuel-rich rocket exhausts. Boundary layer temperature, velocity, and concentration profiles calculated from the Tollmein equations for a number of cold and hot air jets and for rocket engines under various conditions are presented. The most interesting feature of a rocket engine exhaust is the continued high mixing layer temperature as the altitude increases.

Book excerpt: The author's first monograph on turbulent jets, in 1936, dealt solely with a free submerged jet. Since that time, the theory of the turbulent jet has been developed in many published works both in the USSR and abroad: it has been enriched with a large amount of experimental material and has been applied in many new fields of engineering. In the last 10 years very substantial progress has been made, and it has now become possible to go beyond the free submerged jet and to solve the problem of a jet in a stream of fluid, to take into account the interaction between the jet and solid walls, to ascertain the relationship between the contour of the jet and the ratio of its density to the density of the surrounding medium, and to establish the characteristic features of a supersonic jet. This monograph contains the results of further research by the author and his colleagues, as well as a critical reappraisal of the more important theoretical and experimental data published by other investigators. The first section deals with the theory of a turbulent jet of incompressible fluid. It gives a systematic analysis of numerous experimental data on velocity profiles, temperature, and the impurity concentration, as well as the outlines of the turbulent mixing lone. The second section sets forth the theory of turbulent gas jets, including strongly preheated and supersonic jets. The theory of free turbulence in a gas, suitable in principle for any degree of compressibility, is revised, and the equations are derived for motion and heat exchange in the boundary layer of a jet at very high temperature. The third section solves several problems of the spreading of jets in finite and semifinite space, and the fourth section describes various applications of the theory of jets, many of which are reported for the first time or have been significantly revised.

Book excerpt: A high velocity air jet (primary) was directed into a constant diameter duct where it mixed with a lower velocity concentric air stream (secondary). Experimental measurements of the static pressure distribution, mean velocity profiles and turbulence quantities were taken from the initial location where there was a step change in the primary and secondary velocity profiles to the downstream location where the flow was fully developed. Calculations of the momentum flux and wall shear stress were made using the mean velocity and pressure measurements. (Author).
