Interaction Of Flow Turbulence With Preheat And Reaction Zones In Highly Turbulent Premixed Flames
Abstract
The proposed research topic is expected to have a significant impact on the fundamental understanding of turbulent flow modifications to premixed flame structure with a particular emphasis on characterizing flame broadening and turbulent transport under high-Reynolds number and high-Karlovitz number operating conditions. A new understanding of the mechanisms in which the flow turbulence interacts with and directly modifies thermal and reaction zones and the associated scalar transport has significant importance for the advancement of combustion models, including large-eddy simulation (LES), seeking to describe highly turbulent combustion environments characteristic of high-Reynolds number operating conditions. A major emphasis of the experiments is to achieve spatial resolution comparable to the smallest turbulent length scales such that the kinematic interaction between the turbulent flow and combustion-generated scalars can be directly monitored. To the PI s knowledge, this work will represent one of the highest fidelity experimental campaigns to date directly investigating thermal/reaction zone broadening and turbulent transport.
