    Abstract

    This paper describes the UTwente Aeroacoustic Wind Tunnel including its recent anechoic chamber renovation and commissioning. This testing facilitywas originally built in the 1970’s as a closed circuit/closed test section aerodynamic wind tunnel and converted into an aeroacoustic open jet/closed circuit facility in 2001. In 2018 this aeroacoustic wind tunnel has been further upgraded with a special focus on reducing the anechoic chamber cut-off frequency. In the current configuration, the UTwente Aeroacoustic Wind Tunnel is an open test-section facility equipped with a 132 kW electric motor able to produce flow up to 60 m/s with turbulence intensity below 0.08%. The 0.7 x 0.9 m2 rectangular jet with Reynolds number of 324.000 based on the criteria of 0:1 √S. This test facility can be used with airfoil models with chord of up to 0.30 m, reaching a chord-based Reynolds number of up to 1.2 million. The anechoic chamber measures 6 x 6 x 4 m3 equipped with a combination of wedges and flat absorbers leading to a cut-off frequency of 160 Hz and is commissioned accordingly to the ISO 3745 norm.
