Università degli Studi di Brescia was officially established in 1982, building on previous courses given by the nearby Universities of Milan, Milan Polytechnic, and Parma. When it was founded, the University gathered three Schools: Engineering, Economics and Medicine. The School of Law was added in 1996. As a result, since November 1, 2012, the University of Brescia comprises eight departments offering quality programs and competitive research in areas related to Engineering, Health, Law, and Economics. With its 550 permanent academic staff, offers 24 undergraduate Degree programs, 17 postgraduate and 7 Doctoral Degree programs. In 2016, about 14300 students were enrolled. At present, Università degli Studi di Brescia counts more than 160 active financed research projects, 40 international and 120 nationally funded projects. 25 projects were funded within the 7th Framework Programme. The University participated in various programs such as FP5, FP6, FP7, COST actions, LIFE+, South East Europe Program, Erasmus Mundus, ACP Water Facility, Civil Justice and is currently participating in 13 projects within Horizon 2020. The support to the SCARABEUS project will be granted by two Full professors and one technician of the Energy Technology Group (ERGO), in the Department of Mechanical and Industrial Engineering. ERGO’s main research activities focuses on the study, analysis, and design of components involved in all the aspects of energy conversion, particularly in case of power plant operating with non-conventional working fluids (ORCs, closed gas cycles, Stirling engines). The main experimental activity of the Group is the assessment of the thermal stability of working fluids for closed cycle engines. This task is carried out in the Fluid Test Laboratory.
MAIN TASKS IN PROJECT
UBS will lead the activities of WP2 devoted to identify the most promising CO2 blending with particular attention to (i) compound identification, (ii) thermodynamic properties definition and (iii) thermal stability measurements.
DESCRIPTION OF ANY SIGNIFICANT INFRASTRUCTURE AND/OR ANY MAJOR ITEMS OF TECHNICAL EQUIPMENT, RELEVANT TO THE PROPOSED WORK
Fluid Test Laboratory
The Fluid Test Laboratory (FTL) is located in the Department of Mechanical and Industrial Engineering, University of Brescia. The main activity carried out in FTL is the assessment of the thermal stability of working fluids for closed cycle engines (ORCs, closed gas cycles, Stirling engines). Within the context of the SCARABEO project, this laboratory will host the thermal stability tests on the most promising fluids identified, as well as the long term thermal stability tests (2000 hours) for the selected CO2-blends. Since such analysis has been performed so far only on pure fluids, the study of the CO2 blends, will rely on a new methodology and an improved experimental apparatus necessary to take into account the different features required to test a binary mixture. A schematic layout of the experimental test rig presently in use, is shown in the figure below. It consist of : (F) muffle furnace, (B) thermostatic bath, (AC) AC power, (R) security relay for the power supply of the furnace, (PID) temperature control panel, (PC) personal computer for the data acquisition and the system control, (E-1) sample cylinder, (E-2) vacuum pump, (E-3) vacuum trap, (E-4) graduated container, (V-1, VAssociated with document Ref.

The measuring section consists of two pressure transmitters with adjustable span, and one type K thermocouple for the measurement of the temperature of the fluid. The pressure transmitters are equipped with an integrated A/D converter device that allows the compensation of the temperature effect on the measuring sensor. The digital signals coming from the acquisition modules are sampled with frequency of 1 kHz and processed in LabVIEW® environment.
