Abstract
Results of modeling the processes in the multisprayer combustion chamber of the gas-turbine engine operating on a gaseous fuel are presented. Two options of the combustion chamber (basic and modernized) are considered. The basic option is analyzed and design shortcomings are revealed. The design is also improved by inserting plugs on the rings of a flue tube, by redistributing openings over the length of the flue tube and by changing the nozzle design. The results of calculations confirm the effectiveness of the measures taken for reducing the concentration of nitrogen oxides in combustion products.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
