The influence of turbulence on the efficiency and reliability of combustion chamber of the gas turbine

ABSTRACT
The article presents the research results related to the influence of turbulence on the efficiency of the combustion chamber of gas turbine. An artificial increase in the intensity of turbulence is considered as a way to improve the formation of a fuel-air mixture. Turbulent flow is formed due to the installation of guide swirlers at the entrance to the device for creating a fuel-air mixture - a micro module. The angle of rotation of the swirler blades is selected. Theoretical research, mathematical software modeling, as well as an aerodynamic experiment have been carried out. As a result, design solutions are provided that significantly increase the efficiency and reliability of the gas turbine combustion chamber. In the course of the study, guide vanes were selected, and their design was established. The recommended swing angle of the swirler guide vanes is 40°. The recommended depth of the fuel injector inside the chamber is 1.0 gauge.
