Verification of the developed computational model of the main combustion chamber of a gas turbine engine

Improving the efficiency of the main combustion chamber by means of control is of current interest. In this paper, the importance of control of the combustion process in the main combustion chamber of a gas turbine engine is proved. A method of analysis of working processes in main combustion chambers is adopted and validated. A computational model of the main combustion chamber of a gas turbine engine is developed using the ANSYS FLUENT software for solving three-dimensional thermal and fluid dynamics problems. The calculation results obtained by the numerical simulation are verified using test data available for serial production gas turbine engines. The results of verification show that the developed computational model allows modeling working processes in controlled combustion chambers of various designs with a high degree of accuracy.
