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
This book provides physical intuition and key entries to the ever-growing body of literature on turbulent reacting flows. It is of a tutorial nature and includes some historical perspective of the theories developed over the past 30 years. A selection of basic and advanced materials is used to build the necessary background and emphasize some of the main concepts that the student or newcomer to the field of turbulent reacting flows should know, thus facilitating further study of specialized research papers and research monographs. A range of exercises is also provided in order to consolidate the student's understanding./a

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 objective of the proposed research project was the analysis of single point closures based on probability density function (pdf) and characteristic functions and the development of a prediction method for the joint velocity-scalar pdf in turbulent reacting flows. Turbulent flows of boundary layer type and stagnation point flows with and without chemical reactions were be calculated as principal applications. Pdf methods for compressible reacting flows were developed and tested in comparison with available experimental data. The research work carried in this project was concentrated on the closure of pdf equations for incompressible and compressible turbulent flows with and without chemical reactions. Kollmann, W.
