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
The purpose of this research is to continue our efforts in advancing the state of knowledge in large eddy simulation (LES), direct numerical simulation (DNS), and Reynolds averaged Navier Stokes (RANS) methods for the computational analysis of high-speed reacting turbulent flows. In the second phase of this work, covering the period 1 Sep. 1993 - 1 Sep. 1994, we have focused our efforts on two research problems: (1) developments of 'algebraic' moment closures for statistical descriptions of nonpremixed reacting systems, and (2) assessments of the Dirichlet frequency in presumed scalar probability density function (PDF) methods in stochastic description of turbulent reacting flows. This report provides a complete description of our efforts during this past year as supported by the NASA Langley Research Center under Grant NAG1-1122.

Book Description
The main objective is to extend the boundaries within which large eddy simulations (LES) and direct numerical simulations (DNS) can be applied in computational analyses of high speed reacting flows. In the efforts related to LES, we were concerned with developing reliable subgrid closures for modeling of the fluctuation correlations of scalar quantities in reacting turbulent flows. In the work on DNS, we focused our attention to further investigation of the effects of exothermicity in compressible turbulent flows. In our previous work, in the first year of this research, we have considered only 'simple' flows. Currently, we are in the process of extending our analyses for the purpose of modeling more practical flows of current interest at LaRC. A summary of our accomplishments during the third six months of the research is presented. Givi, P. and Madnia, C. K. and Steinberger, C. J. and Frankel, S. H. and Vidoni, T. J.
