Procedure for Simulation of Combustion in the Burner Device of the Low-Emission Combustion Chamber
Authors: , , ,
Abstract: This article discusses the problems of gas dynamic processes modeling in the design of burner devices of low-emission combustion chambers of gas turbine engines. Characteristic features of existing physical and mathematical combustion models, turbulence and radiant heat exchange are analyzed. The necessity of developing a technique that allows developing a final model based on existing physical and mathematical models of turbulence, combustion, radiant heat exchange, and chemical kinetics mechanisms, that accurately reflects gas dynamic processes in burner device of low-emission combustion chamber and allows performing practical calculations with a given accuracy, is identified and justified.To achieve this goal, the authors suggest the following:- to conduct filed tests of the burner device under study;- to perform three-dimensional gas dynamic calculations of the burner device under study using the most used models of turbulence, combustion and radiation;- based on the results of calculations and field tests, to perform validation and select the most appropriate models for the formation of the final physical and mathematical model of the burner device under study;- using the final physical and mathematical model to solve a practical problem in order to test the developed simulation procedure.
