Combustion Regimes in Turbulent Non-Premixed Flames for Space Propulsion
Aerospace, 2023 Direct numerical simulations of non-premixed fuel-rich methane–oxygen flames at 20 bar are conducted to investigate the turbulent mixing burning of gaseous propellants in rocket engines. The reacting flow is simulated by using an EBI-DNS solver within an

A Lagrangian-based flame index for the transported probability density function method
Theoretical and Applied Mechanics Letters, 2022 We propose a new flame index for the transported probability density function (PDF) method. The flame index uses mixing flux projections of Lagrangian particles on mixture fraction and progress variable directions as the metrics to identify the ...

Flame front geometry in premixed turbulent flames [PDF]
Symposium (International) on Combustion, 1992 Experimental and numerical determinations of flame front curvature and orientation in premixed turbulent flames are presented. The experimental data is obtained from planar, cross sectional images of stagnation point flames at a high Damkohler number (80) and turbulent Reynolds number of 60.

Dynamics and control of premixed combustion systems based on flame transfer and describing functions
Journal of Fluid Mechanics, 2020 This article describes recent progress on premixed flame dynamics interacting with acoustic waves. Expressions are derived to determine the stability of combustors with respect to thermoacoustic oscillations. The validity of these expressions is general,
