Dynamics of premixed confined swirling flames

Comptes Rendus. Mécanique, 2009
Considerable effort is currently being extended to examine the fundamental mechanisms of combustion instabilities and develop methods allowing predictions of these phenomena. One central aspect of this problem is the dynamical response of the flame to incoming perturbations. This question is examined in the present article, which specifically considers

DNS of turbulence backscatter in a laboratory-scale swirl stabilized aero-combustor

Applications in Energy and Combustion Science
Classical theories of turbulence suggest that the kinetic energy cascade in nonreacting flows has a net transfer of energy from large to small scales. However, previous studies demonstrated that the thermal expansion of premixed flames can reverse the ...

Predicted Thermoacoustic Flame Response at Megawatt Scale in a Near-Stoichiometric Atmospheric Industrial Furnace

Energies
While gas-turbine combustors have received much research attention, the forced response of large atmospheric industrial flames is much less studied. To improve the understanding of thermoacoustic instabilities in industrial combustion systems, the forced

Study of burner geometry effects on non-premixed flame response under acoustic excitation

Journal of Low Frequency Noise, Vibration and Active Control, 2019
The study of the flame under the acoustic excitation contributes to the study of flame self-excited thermoacoustic instability. Although non-premixed combustion is widely used in industry, research on its combustion instability characteristics is ...

Effects of non-premixed CO2 injection pressure on the premixed explosion characteristics of hydrogen-doped natural gas

Baozha yu Chongji
Coal-to-hydrogen is an effective solution for the low-carbon transformation of coal energy. However, transporting hydrogen via the natural gas pipeline network poses significant explosion safety challenges.
