Facilities
The Wind Tunnel sections and a selection of the available equipment is presented.
The total length of the wind tunnel is 32 m and it consists of 3 test sections:
| Section | Width (m) | Height (m) | Max. speed (m/s) |
| 1 | 4.5 | 3.5 | 9.5 |
| 2 | 3.5 | 2.5 | 17.0 |
| 3 | 1.8 | 1.4 | 60.0 |
Test Section 1 (4.5x3.5m)
The first wind tunnel section (largest) is suitable for testing small propellers, wind turbine rotors and fans.

Test Section 2 (3.5x2.5m)
The second wind tunnel section is equipped with a remotely controlled turn table floor and a three directions motor driven remotely controlled traversing mechanism and a high accuracy six-component balance for the measurement of the airloads.

Test Section 3 (1.8x1.4m)
The third wind tunnel section is suitable for basic and applied research applications. It can be used for testing 2D aifoils, aircraft wings, fuselages, model aircrafts, light and heavy vechicles. It is equipped with a high accuracy six-component balance for the measurement of the airloads.
MOREA variety of measuring techniques can be used in the Wind Tunnel with respect to the needs of the examined case:
- A PIV system is available, allowing velocity field measurements on a plain.
- Load measurements are performed using a 6 component balance and a 6 component load pad.
- Localised flow velocity measurements are performed by means of hot wire velocimetry and 7 hole pitot tubes.
- A Laser-Doppler apparatus is available for measuring fluid velocities with the use of laser beams, based on the Doppler frequency shift of the optical signals. The LDA technique has been used in pulsating flows in closed ducts of small dimensions (expanding or contracting and, branching ducts) in which the blood circulation is simulated.
- Multiple channels pressure scanners are available for measuring static pressure distributions on aerodynamic bodies.
- Flow visualizations are performed using smoke and a Laser source, liquid crystals and ΤiΟ2-oil compound.
Next, a selection of the available instrumentation and devices that are used for the abovementioned techniques is presented.
