Abstract:

The purpose of this research is to conduct fundamental investigations of turbulent mixing, chemical reaction and combustion processes in subsonic and supersonic flows. This program comprises experimental, analytical, computational, and modeling efforts, and a diagnostics development and data- acquisition effort, the latter as dictated by specific needs of the experiments. Our approach has been to carry out a series of detailed theoretical and experimental studies primarily in two, well-defined, fundamentally important flow fields free shear layers and axisymmetric jets. To elucidate molecular transport effects, experiments and theory concern themselves with both liquids and gases, primarily in moderate to high Reynolds number flows. The computational studies are, at present, focused at fundamental issues pertaining to the computational simulation of both compressible and incompressible flows. Modeling has been focused on both shear layers and turbulent jets, with an effort to include the physics of the molecular transport processes, as well as formulation of models that permit the full chemical kinetics of the combustion process to be incorporated.
