Book Description
Theoretical and experimental results are reported concerning the problem of heat transfer to bodies when there is turbulence imbedded in the freestream. Both velocity and temperature turbulence are considered and a fully variable density theory is developed. Experiments were conducted in collaboration with NASA/Lewis. Excellent closure of theory and experiment was achieved for the case of no freestream temperature fluctuations. With no data available for comparison. no closure could be achieved for the case of temperature fluctuations, but the theory indicates that the heat transfer effect of this phenomenon is strong. Keywords: Turbulence, Stagnation point, Reacting flows, Heat transfer.

Book Description
Turbulent reactive flows are of common occurrance in combustion engineering, chemical reactor technology and various types of engines producing power and thrust utilizing chemical and nuclear fuels. Pollutant formation and dispersion in the atmospheric environment and in rivers, lakes and ocean also involve interactions between turbulence, chemical reactivity and heat and mass transfer processes. Considerable advances have occurred over the past twenty years in the understanding, analysis, measurement, prediction and control of turbulent reactive flows. Two main contributors to such advances are improvements in instrumentation and spectacular growth in computation: hardware, sciences and skills and data processing software, each leading to developments in others. Turbulence presents several features that are situation-specific. Both for that reason and a number of others, it is yet difficult to visualize a so-called solution of the turbulence problem or even a generalized approach to the problem. It appears that recognition of patterns and structures in turbulent flow and their study based on considerations of stability, interactions, chaos and fractal character may be opening up an avenue of research that may be leading to a generalized approach to classification and analysis and, possibly, prediction of specific processes in the flowfield. Predictions for engineering use, on the other hand, can be foreseen for sometime to come to depend upon modeling of selected features of turbulence at various levels of sophistication dictated by perceived need and available capability.

Book Description
The overall goal of the research was to establish a strong foundation for understanding and predicting the interaction of fluid mechanical processes with chemical reactions in high speed flows. To accomplish this goal, expertise in chemical kinetics, experimental fluid mechanics and combustion, and computational fluid mechanics were brought together to make a systematic attack on turbulent reacting flows at high speed. In particular, the following tasks were established Task 1: High Speed Flow Experiments Including Mixing and Heat Release Task 2: Fundamental Combustion Experiments and Modeling Task 3: The Development and Application of Advanced Optical Diagnostics Task 4: Numerical Simulation Of Reacting Flows At High Speed The report summarizes the goals of the research and the progress made in each of these tasks.

Book Description
Turbulence, 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.
