Abstract: This article describes the transport and the interaction of pulsating entropy waves generated by combustor burners within a high-pressure turbine stage for aeronautical application. Experiments and computational fluid ...

Abstract: First stages of aeronautical high-pressure turbines are subjected to significant inlet distortions generated by the combustor system. These disturbances are characterized by velocity and temperature fluctuations convected ...

Abstract: Centrifugal compressor aeromechanics is playing an increasingly important role in the energy transition scenario, especially when operating with low-molecular-weight gases, such as hydrogen. For these machines, maximum ...

Abstract: With the trend to full decarbonization, a full-hydrogen economy development is a key industrial objective. Gas turbines, currently one of the cleanest fossil fuel-based power generation solutions, provide reliable and ...

Abstract: The study of component interactions in aeronautical engines is a key aspect to improve the aerodynamic, aeromechanical, and thermal performance and to reduce greenhouse gas and noise emissions. In this context, combustor ...

Abstract: The paper discusses the migration, the interaction with the blades, and the attenuation of hot streaks generated by combustor burners, during their propagation within the first turbine stage of aero-engines. Experiments ...
