N2 - The CFD-modeling of synthetic (hydrogen-rich) fuel combustion in a swirling flame was performed. To simulate the turbulent flames with rigorous turbulence chemistry interaction, a PDF combustion model with detailed chemical kinetics was used. The results of numerical simulations were compared with experimental data. The study was carried out for synthetic fuel, which consists of methane, hydrogen, carbon monoxide, carbon dioxide, and nitrogen. The composition of the synthetic fuel was varied due to a change in the molar fraction of hydrogen from 0.4 to 0.8, and due to a decrease in the molar fraction of CO from 0.44 to 0.04. The flame contours, temperature, and NOx emissions were compared between numerical and experimental data. A visual comparison of OH− contours showed good convergence. The discrepancy between the results of experiment and CFD-modeling is about 3% for temperature and less than 7% for NOx emission. The NOx emissions for synthetic fuel and pure methane, hydrogen, carbon monoxide are compared. For all investigated the synfuel compositions, the NOx emission was from 88.9 ppm to 93.1 ppm for synfuel with 0.4 and 0.8 hydrogen mole fraction, respectively.
