The FLEXTURBINE consortium is built around an industrially initiated nucleus: Core representatives of the European turbine industry have joined forces and involved leading European universities and research institutes to address the identified research and technology questions. They will cooperate to achieve the project objectives, sharing experience and know-how and developing results with complementary skills. The following figure outlines the contributions of each partner to the FLEXTURBINE topics and the impact on the future market drivers for flexible energy generation.
The consortium setup comprises all steps of the value chain and thus ensures that the technology is applied as soon as possible. The industrial design capabilities are complemented by selected high profile university departments, which are also involved in modelling activities as well as in preforming rig and component tests.

University of Florence

University of Florence (UNIFI) is one of the largest research and higher education institutions in Italy, with about 1,800 professors and researchers and more than 1,600 Ph.D. and post-doc students. The Department of Industrial Engineering (DIEF) of the University of Florence was born on January 1st, 2013 by merging “Sergio Stecco” Department of Energy 

Engineering with the department of Mechanics and Industrial Technologies in order to increase research capability and teaching offer. The main research areas include energy engineering, turbomachinery, mechanical design and manufacturing, management, applied physics and chemistry. DIEF is carrying out research projects in a wide range of engineering applications: as far as energy transformation is concerned, the main theoretical research activities develop in the area of gas and hydraulic turbines, axial and centrifugal compressors, pumps, combustion chambers, internal combustion engines, plant design and thermodynamics.

The research group involved in FLEXTURBINE is led by Prof. Andrea Arnone and has been working for about 25 years in the field of applied CFD. The core research activity is the development of a CFD flow solver named TRAF, used worldwide by leading companies and research centres (Avio Aero, Termomeccanica, Ansaldo Energia, Advanced Design Technology, VKI). Since 2000 the group has carried out research activities on Computational Aeroelasticity (CA) and Computational Aeroacoustics (CAA) to extend the codes to the prediction of blade flutter and tone noise.

Role in the project

UNIFI expertise relevant to the FLEXTURBINE project concerns: research on applied CA 

and innovative turbomachinery design. The research activity of UniFi will be aimed at computational aeroelasticity analysis. The in-house TRAF code, a Q3D/3D, URANS solver for turbomachinery flows, with flutter analysis capabilities, will be used.

UNIFI will be involved in the flutter analyses of the test turbines and in the calibration and validation of the flutter predictive models.

Personnel involved

 Dr. Lorenzo Pinelli

Dr Pinelli completed his PhD in Energy Engineering at the University of Florence in 2011. 

He is currently a post-doc member of the group led by Prof. Arnone; his research is largely concerned with computational aeroelasticity and aeroacoustics in axial turbomachines. Within the FLEXTURBINE project, Dr Pinelli will be involved in computational aeroelastic simulations.

Prof. Andrea Arnone

Prof. Arnone  has been a member of the School of Engineering at the University of 

Florence since 1990. He is presently Full Professor of Fluid Dynamics and Turbomachinery. He is the current director of the Dept. of Industrial Engineering. His research involves the use of computational fluid dynamics with a special focus on turbomachinery design and analysis. He has developed 2D/3D CFD codes that are currently used by several industries and research centres. Prof. Arnone will direct UNIFI activities in the FLEXTURBINE project.

Dr. Francesco Poli

Dr Poli earned a PhD in Energy Engineering at the University of Florence in 2005. 

He is currently a post-doc member of the group led by Prof. Arnone; his research focuses on computational aeroelasticity and computational aeroacoustics for turbomachinery applications. Within the FLEXTURBINE project, Dr Poli will be involved in aeroelastic numerical simulations and analyses.
