High Speed Compressible Turbulent Combustion: Turbulent Induced Flame Compressibility Dynamics and Production
Abstract
The performance and limitations of Air Force warfighter propulsion systems are severely influenced by the turbulent flame dynamics. At high Reynolds number regimes, the turbulent flame reactions and structures for these systems are directly driven by the local compressibility effects and turbulent vortex dynamics. The fundamental mechanism for turbulent production in these reacting flow regimes is turbulence induced flame compressibility. The scientific objective of this proposal is to investigate how the flame generated turbulence modifies the dynamics of the turbulent flame and reaction rates in the three dimensional turbulent flame regime (X length scale, Y turbulent intensity, and Z compressibility). Turbulent flames in high speed combustion systems are highly confined enduring substantial pressure gradients. This leads to intense flame generated turbulence that significantly influences the system performance and efficiency.
