DOWNLOAD EBOOKTurbulence, mixing and the mutual interaction of turbulence and chemistry continue to remain perplexing and impregnable in the fron tiers of fluid mechanics. The past ten years have brought enormous advances in computers and computational techniques on the one hand and in measurements and data processing on the other. The impact of such capabilities has led to a revolution both in the understanding of the structure of turbulence as well as in the predictive methods for application in technology. The early ideas on turbulence being an array of complicated phenomena and having some form of reasonably strong coherent struc ture have become well substantiated in recent experimental work. We are still at the very beginning of understanding all of the aspects of such coherence and of the possibilities of incorporating such structure into the analytical models for even those cases where the thin shear layer approximation may be valid. Nevertheless a distinguished body of "eddy chasers" has come into existence. The structure of mixing layers which has been studied for some years in terms of correlations and spectral analysis is also getting better understood. Both probability concepts such as intermittency and conditional sampling as well as the concept of large scale structure and the associated strain seem to indicate possibilities of distinguishing and synthesizing 'engulfment' and molecular mixing.

DOWNLOAD EBOOKThe objective of this program is to measure species concentrations and their statistical properties at points in well-characterized chemically reacting turbulent flows. Such measurements are required for (i) testing theories of reacting turbulent systems and (ii) as input to models which predict the behavior of practical combustors. The model chemical reaction being used to study turbulent mixing/reacting flows is the NO/O3 reaction. A photolysis/chemiluminescence technique is used to measure reactant concentrations, (NO) and (O3), and a product concentration, (NO2), simultaneously at points in the flow field. From such measurements, the required statistical quantities, i.e., probability density functions (pdf) and correlations of reactants and product concentrations, are being developed. These data are supplemented by measurements of the turbulence power spectra and intensity at the same points. During this quarter an examination of the signal collection optics has led to readjustments with reduced errors.

DOWNLOAD EBOOKTurbulence in Mixing Operations: Theory and Application to Mixing and Reaction presents a summary of the current status of research on turbulent motion, mixing, and kinetics. Each chapter of this book discusses turbulence in the context of mixing and reaction in scalar fields. Chapters I and III discuss the classification of turbulent reacting systems and the different possibilities in this context. Chapter II reviews the properties of passive mixing. Chapter IV looks at turbulent mixing in chemically reactive flows. Chapter V uses different techniques to make parallel numerical calculations of both mixing and reaction. Finally, Chapter VI reviews turbulence and actual industrial mixing operations. This book will be of great value for chemical and industrial engineers, especially for those interested in turbulent and industrial mixing.
