• A method of calculating the characteristics of atomization of a liquid fuel by pressure swirl atomizers for setting the boundary conditions of injection into the primary combustion area is proposed. Results of simulating CO emission in a model combustion chamber are presented for two variants of the boundary conditions of liquid fuel injection: (1) with the use of the discrete phase model, where the parameters of fuel atomization are obtained by simulating a two-phase flow by the volume-of-fluid method; (2) for comparisons, with the use of the semi-empirical method of calculating pressure swirl atomizers developed by H. Lefebvre. The method of determining the boundary conditions of injection proposed in the paper makes it possible to increase the accuracy of predicting CO emissions by several times as compared to the classical semi-empirical method of calculating pressure swirl atomizers.
