Turbulent partially cracked ammonia/air premixed spherical flames

Fuel Communications
The combustion of ammonia requires, for most energy conversion systems, a combustion promoter such as hydrogen to guarantee the start-up, stability and combustion efficiency.

The Effects of CO2, N2, and H2O Dilutions on NO Formation of Partially Premixed Synthesis Gas Combustion

Cumhuriyet Science Journal, 2019
Oneof the main methods to decrease NO emission during the combustion of gases isthe use of diluents. This study is interested in the effects of CO2,N2, and H2O dilutions in the adiabatic, turbulent,partially premixed combustion of synthesis gas.

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 ...

Effects of porous insertion in a round-jet burner on flame characteristics of turbulent non-premixed syngas combustion

Case Studies in Thermal Engineering, 2019
Synthesis gas (Syngas) is a gaseous mixture that consists of 3 species. It is used in creating synthetic natural gas. In this work, the turbulent non-premixed flame of syngas-air combustion in a round-jet burner is numerically investigated. The burner is

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
