High-Speed Compressible Turbulent Combustion: Turbulent Flame-Vortex Structure And Dynamics

Abstract

The scientific objective of the proposed work is to investigate how the turbulent flame vorticity generation mechanism modifies the dynamics of the turbulent flame in the three-dimensionalturbulent flame regime: length scale, turbulent intensity, and compressibility:1. Determine the role of flame-generated vorticity (baroclinic torque) on the turbulentstructure evolution and length scales in the turbulent compressible flame regime space.2. Examine the influence of baroclinic torque on the turbulent flame dynamics, turbulentenergy/momentum transport, reaction rates, turbulence scales and flame-vortex evolution.3. Understand the interaction dynamics of baroclinic torque vorticity and the turbulent flame.4. Characterize the compressible flame-vortex dynamics local turbulent energy vorticity,flame strain and extinction.
