Computational study of an aerodynamic flow through a turbine engine combustor

The study presents 3-D numerical simulations of aerodynamic flow inside a GTD-350 turbine engine combustion chamber. The process of generating a numerical grid, determining boundary conditions and their properties are described. For the assumed boundary conditions, there were performed numerical simulations of the aerodynamics of cold airflow through the combustion chamber (without fuel supply to the interior) using Ansys CFX code. A numerical experiment was also conducted for the assumed difference of pressure at the inlet to each of the air supplying pipes. The work ends with a discussion of the results, in particular concerning the loss of pressure in the combustion chamber and possible design changes to minimize them.
