The goal of the simulation is to<br />predict the non-uniformity of the combustor exit gas temperature field. The calculations are performedin two settings: a) with the simplified model of a full-size combustor included in the computationaldomain; b) with the one-burner sector of the combustor included in the computational domainand setting periodic boundary conditions. The results of the numerical simulation confirmedthe influence of periodic boundary conditions on the accuracy of prediction of the combustor exitgas temperature field. The full-size combustor calculation is shown to be more appropriate and universalbut more costly than the calculation of its one-burner sector.</p>Gas turbine engineannular combustorflowcombustionnumerical simulationperiodic boundary conditionsgas temperature fieldГазотурбинный двигателькольцевая камера сгораниятечениегорениечисленное моделированиепериодические граничные условиятемпературное поле газа
