Finite Rate Chemistry and NO Molefraction in Non-Premixed Turbulent Flames

Investigations of hydrogen and hydrogen–hydrocarbon composite fuel combustion and emission characteristics in a model combustor

“…Temperature distributions and the maximum levels in the combustor and the average levels at the combustor exit show similar trends with the experimental results [11][12][13][14][15] and other numerical works [16][17][18][19][20][21]. The overall flame temperature decreases as methane is added to the fuel because of the lower energy input.…”

“…Experimental results, temperature and gas concentration measurements on similar combustors were taken from the literature [11][12][13][14][15]. In addition to the existing experimental results, some temperature and gas concentration measurements were also carried out at the combustor exit for comparison with CFD model predictions.…”

Hydrogen as burner fuel: modelling of hydrogen-hydrocarbon composite fuel combustion and NOx formation in a small burner

“…The effect of mixture ratio on the hydrogen combustion was also investigated. Inlet air temperature and fuel temperature were 300 K. Experimental measurements are very limited on hydrogen combustion and NO x emissions in burners (Tomczak et al, 2002;Neuber et al, 1998;Chen, 1998;Choudhuri and Gollahalli, 2003a,b). The available average measured values of temperature, NO and CO concentrations at the combustor exit are obtained from our previous work (Ilbas et al, in press) and presented in Table III for comparison with the predictions.…”

“…They have also shown that hydrogen-natural gas composite fuel is a good alternative for gas turbine combustors. Neuber et al (1998) have performed numerical and experimental study on turbulent diffusion combustion of pure hydrogen fuel. They have used the standard k-e model for the modelling of turbulent flow in combustor, and reported that the model gives well flow predictions.…”

Laser diagnostics and their interplay with computations to understand turbulent combustion

“…1, target flames have been selected to cover a progression in complexity, starting with simple jet flames of H 2 , H 2 /He, and H 2 /N 2 in air (not shown) [72][73][74][75]. Dilution with N 2 or He reduces flame temperature, minimizing the influence of radiation on NO formation and better isolating the effects of turbulence-chemistry interaction.…”
