Abstract
In the design and analysis of gas turbines, Computational Fluid Dynamics (CFD) is nowadays widely used to analyze separately components of the engine, employing specialized flow solvers for every component.When the flow in turbine is studied, RANS and URANS approaches are usually employed. On the other hand, when the flow in a combustion chamber is analyzed, aLES approach demonstrates to be more accurate and the only way to properly handle flame instabilities,which are one of the main problems affecting modern lean combustors.
