Abstract
The article contains the results of experiments on the research of aerodynamic parameters in the cylindrical module of the combustion chamber in a gas turbine. The intensity of turbulence and flow velocity are considered in the article as the main factors affecting the efficiency of the formation of the fuel-air mixture and, as a consequence, the efficiency of its subsequent combustion. The air flow is studied under isothermal conditions inside two cylindrical channels of different diameters with swirl blades at the inlet. Turbulence intensity and flow velocity are obtained for various points inside the channel. The graphical format for the result presenting was chosen as the most convenient for understanding. The factors influencing the value of intensity and speed are given on the basis of the analysis of experimental data. The study of the structure of the air flow in the channels gives us the opportunity to determine the fuel injection zones. The article may be of interest to researchers and specialists in the field of power and aerodynamics.
