Computational study of a combustion process in a turbine engine combustor

A computational study of the combustion process in a GTD-350 turbine engine combustor is presented. The numerical grid generation process and the optimization of its density are described. For the assumed boundary conditions, numerical simulations of fuel dispersing, mixing and combustion process in the combustor were performed with the use of Fluent code. The numerical simulations were conducted for different cone angles of spraying fuel and for different mean droplet diameters of fuel spray. The work ends with the discussion of results, in particular concerning the quality and stability of the combustion process in the engine combustor.
