Influence of the burner form on the combustion chamber outlet temperature field ripple for different modes of operation of gas turbine engines

Abstract


This article describes a method of identifying combustion chamber temperature field ripple by the preparation of the set of nozzles in the engine. It shows combustion chamber temperature field ripple with a divergent nozzle and a convergent one used in the burner. The design of the combustion chamber and that of the burners are described. Diagrams are plotted that show variation in circular and radial temperature field ripple depending on the engine behavior. The combustor exit temperature field non-uniformity is assessed using such parameters as the overall temperature distribution factor, the radial temperature distribution factor and the circumferential temperature distribution factor. Comparative analysis of the results of testing two combustion chambers with different modifications of burners is carried out. Conclusions about the effect of the burner design on the temperature field ripple are made.
