Turbulence Evolution Through Premixed Flames and its Relationship with Flame Structure

Abstract

The proposed experimental research program will measure the evolution of turbulence through highly-turbulent premixed flames and the resultant coupling with the flame dynamics. The overarching objectives are to:1) advance the state-of-the-art in combustion diagnostics, particularly 4D microscalevelocimetry and simultaneous vector/scalar measurements;2) provide experimental data with resolution and fidelity as close as possible to directnumerical simulations (DNS), but in realistic flames; and3) quantify the material derivative of dynamic turbulence properties (e.g. enstrophy, strainrate)as the turbulence interacts with a premixed flame, the relative importance of thesource terms controlling the turbulence evolution, and how these source terms dependon/interact with the flame scalar structure.
