Acoustic wind tunnel
In the WindLab at the University of Oldenburg
Ready for the major challenges of wind energy research
The acoustic wind tunnel is designed as a closed-loop wind tunnel. It has a cross-section of 1 m x 0.8 m, is soundproofed and can be operated either with a closed test section of 2.7 m or an open test section of 2.0 m in length at wind speeds of up to 50 m/s. Various active grids can be used to generate customized wind conditions (emulated from atmospheric measurements or designed for specific turbulence characteristics). High-resolution measurement techniques (hot-wire, stereo PIV, 2D LDA, pressure sensors, force balances) can be used in various applications. Blade profiles can be tested for re-numbers up to 1,000,000. Model wind turbines with rotor diameters of up to 0.6 m are available for testing.
