Lab full name

Laboratory for wave energy conversion devices and Wells turbines

ERC 2nd Level Code

PE8 Products and Processes Engineering

PE1 Mathematics

ERC 3rd level Code

PE8_5 Fluid mechanics, hydraulic-, turbo-, and piston engines

PE8_6 Energy processes engineering

Research Activities

This laboratory is devoted to the performance analysis of Wells turbines to be included in systems
OWC systems (Oscillating Water Column) for wave energy harvesting.
For these studies a test bench (specifically designed), is used, which reproduces the conditions of
the air flow generated by the wave motion. The entire system is remotely controlled via software,
determining the operating conditions.
The test rig consists of: a suction centrifugal fan controlled by a Variable-Frequency Drive
(VFD); a straight pipe where a diaphragm is housed for flow measurement; a plenum chamber; a
second straight duct in which is located the AC Brushless Servo Systems connected to the torque
transducer (for torque measurement) and to the Wells turbine.

Research Activities

In the area named Ex-Officine Scianatico, thanks to funding from the PrInCE project, the Politecnico di Bari University transferred the soundproof chamber inside of which two test benches housing internal combustion engines (already available). Moreover, a methane pipe has been added, which will allow to carry out studies of small CHP units based on internal combustion engines of automotive derivation.
The first test bench is equipped with a single 500 cm3 cylinder research engine, 4-stroke, spark ignition (with both bore and stroke equal to 86 mm), model 5401 produced by AVL. The engine compression ratio is 10.5: 1. The engine has 4 valves, and a Bosch injector that injects, at closed valves, in the intake duct. The dynamometer consists of an eddy current brake with oscillating cradle and load cell, model System One Alpha 160, rather sophisticated. This implements: oil and water cooling systems (heat exchangers with SIEMENS automated valves); Electric starter (3.2 kW); throttle actuator (stepping motor); Cabinet for cabling of additional acquisition data (Automation Unit); basic data acquisition system (pressure sensors and PT100 thermocouples; pressure transducers and flow switches); internal system for cooling the water of the brake refrigeration system; open access Engine Control Unit (ECU) with maps for early injection and spark ignition and injection, which can be changed in real-time; acquisition system of the indicated cycle; gravimetric balance.
The second test bench is as follows: an eddy AVL Alpha 240 (maximum output current: 240kW, maximum speed: n = 10000rpm); HBM U2A load cell for detecting the torque; feeder LSE AVL 435 for the excitation of the dynamometer; loop detection; detecting the composition of exhaust gas; fuel system. The engine currently under investigation is an Alfa Romeo 2.4 JTD 10V, 5-cylinder, one head camshaft (motor code AR32501; 2387cm3; 90.4mm stroke; 82mm bore; compression ratio 18.5:1; maximum power 100kW @ 4200rpm, maximum torque 304Nm @ 2000rpm; Bosch’s direct fuel injection system with an electronic "Common Rail" controller, EDC-15C.

Research Activities

The subsonic closed loop wind tunnel of the GAVE Lab has a 1 meter squared test section.
The wind tunnel is of rectangular shape, is 30 m long, and has a sufficient length to ensure the uniformity of the flow across the test section. The wind tunnel can be divided into four different zones: the first zone (downstream the test section) includes a diverging portion of increasing rectangular section, whose task is to recover part of the kinetic energy; two (90deg) curves follow, guiding the flow toward the inlet of the fan. Upstream the fan, orifices are provided in order to prevent the wind tunnel pressurization due to the air heating during steady state operation. The second zone is constituted by the axial fan, which is driven by a three-phase AC motor (55kW) mounted on a special cradle inside the cylindrical duct which encloses the impeller. The possibility to adjust the engine rotation speed by means of a Variable-Frequency Drive (VFD), allows one to obtain variable speed in the test section, and then to recreate different operating conditions. The third zone, located downstream the fan, includes other two curves (this time with guide vanes), that allow the curvature of the flow without introducing flow distortions or significant secondary flows. Finally, a convergent duct (with a contraction ratio equal to 4:1) accelerates the flow up to the rated speed on the input section of the test area (this is subsonic wind tunnel, then air can be considered incompressible). Upstream the convergent there is an "honeycomb", in order to make the flow uniform (elimination of any macro-turbulence). The last zone is constituted by the test section composed with side walls made of transparent polycarbonate. This material allows one the use of non-intrusive laser measurements. Moreover, its structure consists of a Rexroth aluminum frame. In the test section, a three-axis Cartesian robot controls the position of a hot-wire probe for measuring the wind speed. The upper closure panel of the test volume is formed, therefore, by two polycarbonate half-panels, between which is inserted the wind speed probe; the two panels are movable, in order to allow the horizontal displacement of this probe.
The three-axis Cartesian robot is basically composed of the following elements: stepper motors; control and driving boards; profiles and guides (traversing).
