Fluid-dynamics of turbomachines

The research group working at the Lab. of Fluid Machines (LFM) of the Dipartimento di Energia is active in the field of experimental and numerical Fluid Dynamics, with particular emphasis on turbomachinery for both compressible and incompressible fluids.
The laboratory is equipped with a number of large-scale and advanced facilities for experimental research: two wind tunnels for testing transonic and supersonic cascades, a high-speed closed-loop test rig for turbine and compressor stages up to 800 kW of power, a closed-loop rig for testing annular turbine cascades up to transonic conditions, a test-rig for studying the supersonic flow of organic vapors, and a test rig for hydraulic turbines and pumps up to 100 kW of power. The available measurement techniques range from classical HWA and multi-hole directional probes, to the most advanced single and multi-hole Fast Response Aerodynamic Pressure Probes (FRAPP) and optical systems such as Schlieren, two-components LDV and PIV. The section of Computational Fluid Dynamics (CFD) has developed several in-house codes for the calculation of the flow field, the prediction of the performance, the design and optimization of turbomachinery components. The section has also gained relevant experience in the application of the most common commercial codes, such as Ansys-Fluent and Ansys-CFX. The LFM owns and manages a cluster for High Performance Computing (HPC).
The several research contracts carried out for major national and international companies (examples are Franco Tosi Meccanica S.p.a., GE Oil & Gas - Nuovo Pignone, EDF, Ansaldo, Turboden) as well as the relevant research funding achieved by the LFM group during its history (PRIN 2007, PRIN 2009, Regione Lombardia 2010, Fp7-RECORD 2013 to cite the most recent) demonstrate the recognized capabilities of the research group.
Among the facilities, a modern test section is also available for the industrial characterization of safety valves operating in both air and water with atmospheric, assigned and generated back-pressure. The facility is fully automated, it is run by a highly specialized technician, and it is commonly employed for R & D testing or product certification of safety valves.
