摘要: Recent advances in computer science and highly parallel algorithms make Large Eddy Simulation (LES) an efficient tool for the study of complex flows. The available resources allow today to tackle full geometries that can not be installed laboratory facilities. present paper demonstrates state art LES allows simulations combustion chambers with one, three or all burners results may differ considerably from one configuration other. Computational needs issues such are discussed. A single burner periodic sector a triple annular chamber gas turbine investigated assess impact periodicity simplification. Cold flow validate this approach while reacting underline differences results. acoustic response set-up is totally different both cases so geometry seem requirement instability studies.
