Design of a quiet open jet facility for the measurement of aerofoil noise
This paper presents the design and measured characteristics of a large-scale open jet wind tunnel newly commissioned in the large anechoic chamber at the ISVR, University of Southampton in the UK. The wind tunnel is primarily designed for the measurement of airfoil trailing edge self-noise. The wind tunnel is designed to have low turbulence levels and low acoustical noise background at flow speeds of up to 100m/s. The air is supplied from compressed air tanks that provide constant flow speed over a time period of up to 90s. The air discharges from a rectangular jet nozzle of an area of 150 x 450mm. Aerodynamic and acoustic calibrations of the open jet wind tunnel were performed. It is found that the potential core is characterized by a low turbulence intensity of about 0.1%. The background noise level is also found to be lower than the predicted trailing edge self-noise of a NACA0012 airfoil at 0° angle of attack over a wide band of frequencies. This facility is believed to be the first of its kind in the UK.

Abstract

This paper presents the design and measured characteristics of a large-scale open jet wind tunnel newly commissioned in the large anechoic chamber at the ISVR, University of Southampton in the UK. The wind tunnel is primarily designed for the measurement of airfoil trailing edge self-noise. The wind tunnel is designed to have low turbulence levels and low acoustical noise background at flow speeds of up to 100m/s. The air is supplied from compressed air tanks that provide constant flow speed over a time period of up to 90s. The air discharges from a rectangular jet nozzle of an area of 150 x 450mm. Aerodynamic and acoustic calibrations of the open jet wind tunnel were performed. It is found that the potential core is characterized by a low turbulence intensity of about 0.1%. The background noise level is also found to be lower than the predicted trailing edge self-noise of a NACA0012 airfoil at 0° angle of attack over a wide band of frequencies. This facility is believed to be the first of its kind in the UK.
