Chemical Reactions in Turbulent Mixing Flows
Abstract
The purpose of this research has been to conduct fundamental investigations of turbulent mixing chemical reactions and combustion processes in turbulent, subsonic supersonic flows. This program is comprised of several efforts. In particular, an experimental effort, an analytical effort, a modeling effort, a computational effort and a diagnostics development and data- acquisition effort -- the latter as dictated by specific needs of the experimental part of the overall program. 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. Modeling efforts have been focused on both shear layers and turbulent jets with an effort to include the physics of the molecular transport processes, as well as formulations of models that permit the full chemical kinetics of the combustion process to be incorporated. Our recent analytical efforts have concentrated on a hydrodynamic analysis of the stability of compressible shear layers. The computational studies are, at present, focused at fundamental issues pertaining to the computational simulation of both compressible and incompressible flows. (aw)
