In the present work, the turbulent flow fields in a static and rotating ribbed channel representative of an aeronautical gas turbine are investigated by the means of wall-resolved compressible large-Eddy simulation (LES). This approach has been previ

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 Simulation of a combustion chamber simulator along with its high pressure turbi

In a gas turbine, the combustor is feeding the turbine with hot gases at a high level of turbulence which in turns strongly enhances the heat transfer in the turbine. It is thus of primary importance to properly characterize the turbulence properties

One of the state-of-the-art system for turbine blade trailing edge cooling consists in blowing air, coming from the internal cooling system of the blade, through slots over a cutback on the pressure side. To increase the stiffness, this cutback is co

The accurate description and flow calibration at the exit of a gas turbine combustor is a key point of turbine design. Indeed, the temperature field at the turbine inlet directly impacts both the work extraction by the turbine stages as well as drive
