This book was released on 2013-03-08 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: It was on a proposal of the late Professor Maurice Roy, member of the French Academy of Sciences, that in 1982, the General Assembly of the International Union of Theoretical and Applied Mechanics decided to sponsor a symposium on Turbulent Shear-Layer/Shock-Wave Interactions. This sympo sium might be arranged in Paris -or in its immediate vicinity-during the year 1985. Upon request of Professor Robert Legendre, member of the French Academy of Sciences, the organization of the symposium might be provided by the Office National d'Etudes et de Recherches Aerospatiales (ONERA). The request was very favorably received by Monsieur l'Ingenieur General Andre Auriol, then General Director of ONERA. The subject of interactions between shock-waves and turbulent dissipative layers is of considerable importance for many practical devices and has a wide range of engineering applications. Such phenomena occur almost inevitably in any transonic or supersonic flow and the subject has given rise to an important research effort since the advent of high speed fluid mechanics, more than forty years ago. However, with the coming of age of modern computers and the development of new sophisticated measurement techniques, considerable progress has been made in the field over the past fifteen years. The aim of the symposium was to provide an updated status of the research effort devoted to shear layer/shock-wave interactions and to present the most significant results obtained recently.

Available in PDF, EPUB and Kindle. Book excerpt: Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.

Available in PDF, EPUB and Kindle. Book excerpt: This report reviews presentations given at the September 1985 symposium of the International Union of Theoretical and Applied Mechanics and concludes that calculation of two-dimensional shock-wave/boundary-layer interaction problems is advancing well. For three-dimensional flows, accurate numerical calculation needs more experimental data to clarify the mechanisms and flow structures involved. Of greatest priority in this area is obtaining accurate unsteady measurements so that the mechanisms of shock oscillation and its results on the flow field can be better understood. Keywords: Boundary layer, Fluid mechanics, Fluid dynamic properties, and Boundary value problems.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the results of research into the interactions between shock waves and turbulent flows using numerical simulations. The research was conducted at transonic speeds with a normal shock wave and two dimensional turbulence, making use of existing knowledge and computational methods for developing insight to the shock/turbulence interaction. The results indicate that the shock has a significant effect on the turbulence. The shock produces a jump in the turbulence statistics, with a long relaxation distance to return to unshocked values. The turbulence kinetic energy is increased by as much as 30 percent by the shock. The density-velocity correlation becomes important during the shock jump and is greatly increased over the case without a shock. On the other hand, the pressure-velocity correlation is not so important. The shock speed and ripple were found to be important factors in determining the turbulence downstream of a shock wave. Shock speed and ripple correlations are the same size as other important turbulence correlations. The work must be extended to higher Mach numbers and three-dimensional turbulence, with oblique shocks and shear flows. The shock ripple may be more important for oblique shocks because of the larger v component. (jhd).

This book was released on 1999 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Significant contributions were made in a four-year interdisciplinary experimental, numerical and theoretical program to extend the state of knowledge and understanding of the effects of chemical reactions in hypervelocity flows. The program addressed the key problems in aerothermochemistry that arise from the interaction between the three strongly nonlinear effects: Compressibility; vorticity; and chemistry. Results included: (1) Discovery of dramatic damping effects of nonequilibrium vibration and chemistry on transition in hypervelocity flows; (2) Proper formulation of parameters for reacting blunt-body flows. (3) Effects of nonequilibrium chemistry in shock-on-shock interaction; (4) New experiments on, and correlation with theory of high-enthalpy flap-induced separation; (5) Computations of interaction of a shock wave with density interfaces and with compressible Hill's spherical vortex; (6) Extensive clarification of phenomena in supersonic shear flows using new diagnostic and computational tools; (7) New experiments and computations of hypervelocity double-one flow yielded insights into vibration-dissociation coupling; (8) First-principles computations of electron collision cross-sections with diatomic molecules and CO2; and (9) Development of new diagnostic technique LITA for accurate non-intrusive point measurement of gas properties.

Available in PDF, EPUB and Kindle. Book excerpt: This edited monograph contains the proceedings of the International Shock Interaction Symposium, which emerged as an heir to both the Mach Reflection and Shock Vortex Interaction Symposia. These scientific biannual meetings provide an ideal platform to expose new developments and discuss recent challenges in the field of shock wave interaction phenomena. The goal of the symposia is to offer a forum for international interaction between young and established scientists in the field of shock and blast wave interaction phenomena. The target audience of this book comprises primarily researchers and experts in the field of shock waves, but the book may also be beneficial for young scientists and graduate students alike.

Book excerpt: Linear analysis and direct numerical simulation (DNS) are used to study the interaction of a shock wave with a turbulent flow. Effects central to shock wave/boundary layer interaction are identified and explained. The quantitative importance of the turbulence anisotropy and the shock oblique angle is demonstrated. Drop in Reynolds shear stress across a normal shock is shown. The implication for Reynolds stress models is discussed. The role of dilatational turbulent fluctuations on turbulence amplification is studied in detail. An explanation is suggested for lower amplification reported in wind-tunnel studies. Linear analysis & DNS are used to demonstrate the considerable influence of entropic fluctuations on turbulence evolution across a shock. Positive correlation between u' and T ' suppress amplification while negative correlation enhances it. Invalidity of Morkovin's hypothesis is demonstrated. A high order scheme is developed to allow strong shock/turbulence interaction. Results are presented for isotropic turbulence/normal shock interaction. (AN).

Available in PDF, EPUB and Kindle. Book excerpt: The interaction of a convected field of turbulence with a shock wave has been analyzed to yield the modified turbulence, entropy spotiness, and noise generated downstream of the shock. This analysis generalizes the results of Technical Note 2864, which apply to a single spectrum component, to give the shock-interaction effects of a complete turbulence field. The previous report solved the basic gas-dynamic problem, and the present report has added the necessary spectrum analysis.
