Analysis of gas temperature fields at the outlet of combustion chambers of small gas turbine engines

The paper analyses the peculiarities of gas temperature field formation for combustion chambers of small gas turbine engines. A more precise model for calculating hydraulic resistance coefficient has been developed. The results concerning the impact of combustion chamber design parameters on the nonuniformity of gas flow temperature field are presented. Recommendations for design and finishing of this unit in small gas turbine engines are given.
