Abstract

The results of modeling the working processes in the combustion chamber of a gas turbine engine operating with gaseous fuel are given. Two modifications of the combustion chamber—the one equipped with a nozzle that has a jet gas supply and the other one equipped with a nozzle that has a swirling gas supply—are considered. The intrachamber processes are calculated using the EddyDissipationConcept, FiniteRate/ EddyDissipation, and NonPremixed_flamelet combustion models. As determined from the calculation results, the arrangement of a jet fuel supply enables the most efficient combustion of gaseous fuel. The EddyDissipationConcept model is a combustion model that has shown the CO and NOx emission values closest to the experimental data.
