Abstract
The effect of applying a Kutta-Joukowski condition at the edges of an absorbing strip which is generating noise in a turbulent fluid at low Mach numbers is examined. It is found that the presence of fluid flow attenuates the sound level in the shadow region of the absorbent screen. There is greater attenuation of the sound level in the trailing edge (wake present) situation than there is for the leading edge (no wake present) situation. Physical interpretation of the results is then discussed.
