抜粋

The present paper describes an experimental work to reduce supersonic jet noise using a cross wire device that is placed into the supersonic jet stream. The cross wire device is composed of long cylinders with a very small diameter. The location of the wire device is varied to investigate the control effect of supersonic jet noise. A high-quality schlieren optical system is used to visualize the flow field of supersonic jet with and without the wire device. Acoustic measurement is performed to obtain the overall sound pressure level and noise spectra. The results obtained show that the present wire device breaks the shock-cell structures, reduces the shock strength, and consequently leading to considerable suppression of supersonic jet noise. The location of the wire device is an important factor to obtain the noise reduction. The present wire device suppresses the screech tones and the broadband shock-associated noise as well as the overall sound pressure level, when it is suitably placed at a location closer than 3 times the exit diameter of nozzle.
