The adoption of lean-burn technology in modern aero-engines influences the already critical
aerothermal conditions at turbine entry, where the absence of dilution holes preserves the …

In order to deepen the knowledge of the interaction between modern lean burn combustors
and high pressure turbines, a real scale annular three sector combustor simulator has been …

With the generalization of Lean Burn combustors, the flow field entering the turbine tends to
feature higher levels of swirl, turbulence, while different hot streak patterns often emerge if …

Modern lean burn aero-engine combustors make use of relevant swirl degrees for flame
stabilization. Moreover, important temperature distortions are generated, in tangential and …

The analysis of a combustion chamber effects on the aerodynamics and thermal loads
applied on a turbine stage is proposed. To do so, an integrated wall-modeled Large-Eddy …

The accurate prediction of the fluid dynamic conditions at the exit of gas turbine combustors
are of paramount importance in the aero-thermal design of the aero-engine. In fact, both the …
