NUMERICAL SIMULATION OF HIGH PRESSURE BURNER WITH PARTIALLY PREMIXED FLAME

open access: yesCT&F Ciencia, Tecnología & Futuro, 2011
In this paper we present the results of a 2D axisymmetric parametric study which simulates an atmospheric premixed burner with flame at high pressure, in which methane is burned.

Dynamics of Thermoacoustic Oscillations in Swirl Stabilized Combustor without and with Porous Inert Media

open access: yesJournal of Combustion, 2022
Lean premixed (LPM) combustion processes are of increased interest to the gas turbine industry due to their reduction in harmful emissions. These processes are susceptible to thermoacoustic instabilities, which are produced when energy added by an in ...

Influence of air-assisted atomizer structure on ignition and flame propagation in a trapped-vortex cavity

open access: yesCase Studies in Thermal Engineering, 2022
This study explores the application of a partially-premixed and pre-evaporated air-assisted fuel supply device used in a trapped-vortex cavity. The lean-ignition fuel-air ratio (FAR) was measured under different device structures, total pressures, and ...

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

open access: yesApplications 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 ...

Effect of Different Acoustic Parameters on NOx Emissions of Partially Premixed Flame

open access: yesApplied Sciences, 2019
The effects of acoustic frequency (f)/0–400 Hz and amplitude (A)/0–1400 Pa on nitrogen oxides (NOx) emissions of a partially premixed flame were investigated experimentally.
