Obiettivo del progetto (Objective)
'ACTREAL aims to deliver aerodynamics research enabling aeroengine turbine efficiency increase in order to reduce greenhouse gas emissions. The aerodynamic loss in low-pressure turbines are largely accountable to flow separation in cruise conditions, the situation being more critical with nowadays ultra-high-lift blade design trends, hence increasing fuel consumption rates, thus emissions. Active flow control is a promising technology to suppress separation thus reducing losses, which has been demonstrated effective but still some open questions hamper its industrial application in turbomachinery. This project aims to contribute to the likelihood of extensive adoption by considering real machine effects on flow active control which have not been yet investigated. The main objective of the project is to verify the effectiveness of active flow control and optimize control parameters for UHL LPT efficiency increase in real stage environment. Real machine effects must be estimated as rotor-stator interaction, radial cascade, proper periodicity and compressibility through experimental campaign -in the third country organization linear cascade wind tunnel- supported by numerical simulations by computational fluid dynamics tools. In facing this, assessment of numerical and experimental methodologies suitable for active control is carried out. Deep knowledge of fluid dynamics mechanisms of separation control in this environment are pursued by experiments and high accuracy numerical simulations as Large-Eddy-Simulation. A preliminary study of a feasible mechanical technology to engineer active control without the use of electronic equipmenta will be undertaken. The contribution to EU scientific and technological knowledge and researcher training will be enhanced by taking advantage from the large experience and outcomes attained by the third-country organization in the field of active control applied to turbomachinery.'
