6 FAQs about [Wind turbine wind tunnel 45 meters high]
How fast can a wind tunnel go?
The airspeed reaches to a maximum of 105 m/s in the test section. With a model chord length of 0.9 m, this wind tunnel can go up to a Re number of 6 × 10 6. The airfoil models are positioned horizontally in between two turntables on both sides of the test section.
What is a wind tunnel?
It has been designed specifically for aerodynamic and aeroacoustic testing of airfoils and rotors. It is a closed-return tunnel with maximum flow speeds of up to 378km/h, similar to three-time hurricane strength. The combination of test possibilities makes the wind tunnel one of a kind, not just nationally but globally.
Why is wind tunnel testing important?
Wind tunnel testing of airfoils is an indispensable part of the wind turbine design process. Especially very large wind turbines with 100m+ blades demand robust airfoils with highly accurate aerodynamic data during the design phase which requires special attention for wind tunnel testing.
What is the re number of a wind tunnel?
With a model chord length of 0.9 m, this wind tunnel can go up to a Re number of 6 × 10 6. The airfoil models are positioned horizontally in between two turntables on both sides of the test section. These turntables are used to position the model in the test section correctly and also to control the angle of attack variations during testing.
Which wind tunnel is used for wind turbine airfoil testing?
One of the most commonly used wind tunnels for wind turbine airfoil testing is Technical University of Delft Low-Turbulence Tunnel in the Netherlands. It is a closed-circuit atmospheric wind tunnel with a 1.25 m × 1.80 m × 2.60 m (h × w × l) test section as in Fig. 4.
How big is a wind tunnel?
This wind tunnel, shown in Fig. 1, has a test section with dimensions of 0.9 m in width, 2.29 m in height, and 2.29 m in length. With a motor of about 1.5 MW power, the airspeed in the test section could reach a Mach number of 0.47.
