High Speed Turbulent Mixing and Combustion
Abstract
Advanced hypersonic air-breathing and hybrid engines utilizing subsonic/supersonic combustion, and high energy lasers, are required for effective weapon systems in future aerospace missions. The overall objective of this program is to investigate the turbulent mixing and combustion processes required for these advanced systems. Results of these studies will assist in engineering design and development of practical injection-mixing systems and combustion chambers for the advanced propulsion systems, as well as providing critical design input for development and optimization of high energy chemical lasers. The following theoretical one experimental studies for homogeneous and heterogeneous highspeed turbulent mixing and combustion in subsonic and supersonic streams are reported. (1) An analytical study of turbulent reacting flows with mass, momentum, and energy transfer. (2) Experimental and analytical study of gas-particle, turbulent mixing and reacting flow with non-tangential particle injection. (3) Analysis of injection of non-homogeneous and heterogeneous fuels into uniform supersonic and subsonic streams, and (4) A review of existing experimental data and analytical methods, concerning turbulent mixing and combustion. Objectives of this research are to: (1) Determine effects of chemical reaction, mass, momentum, and energy transport on flow field development of coaxial jets and ducted flows. (2) Develop necessary analytical tools for predicting gas-particle mixing and combusting flow systems. (3) Investigate scaling parameters, pressure gradient shock losses, and initial jet penetration versus downstream turbulent diffusion for the transverse mode of injection, and (4) Determine the adequacy and applicability of existing two-stream mixing data and analytical techniques.
