Laboratory Renewable Energy Sources ”Mircea Dimitrie CAZACU”

The topics approached in the Laboratory of Renewable Energy Sources "Mircea Dimitrie CAZACU" (LSRE "Cazacu") lies in the field of capturing and conversion of energy from renewable sources, mainly wind, solar, hydraulic and waves, and geothermal, respectively. The use of hydrogen energy obtained through non-polluting processes, unconventional energies such as vibration, bioenergy or energy recovery systems is also being studied.

The most representative machines and installations that are studied in LSRE "Cazacu": turbines and wind systems such as those with horizontal or vertical axis (Savonius and Darrieus type or combinations between them); hydrokinetic turbines for running waters of axial type or crow-flow type (Banki type); tidal energy generation and capture installations; solar thermal collectors for water and air with and without energy storage; photovoltaic panels of various compositions including flexible base; direct fuel cells (with methanol or low concentrated fuels); hybrid installations containing combinations of these systems as well as unconventional applications.

The activities from this laboratory refer to the explanation of the structure and operation of these machines and installations and consist practically in the determination of their functional performances directly by the students under the guidance of the teachers.

In LSRE "Cazacu" there are more than 20 test rigs that use: an aerodynamic tunnel with air speeds of up to 40 m/s, a wind tunnel with free vein equipped with a propeller with a diameter of 2 m; wave channels equipped for their energy conversion; a wind tunnel open designed for air testing of hydrokinetic turbines; light sources for the study of solar energy conversion. The rigs are equipped with high-performance equipment, to which are added additional equipment: 3D printers and 3D scanners, along the computer network and appropriate software.
