Abstract The radiation of sound from geometrically simple vibrating structures into stationary fluids is well understood. However, to date, very few investigations have considered the effects that a convected fluid has on structural acoustic radiation. The purpose of this investigation is to quantify the effects of changes in flow velocity on the sound radiated from a vibrating elastic plate into a convected fluid medium. The discussion will include a description of modeling an elastic plate imbedded in an infinite baffle and radiating into a semi-infinite convected fluid field. Furthermore, the importance of a coupled model approach (where the fluid pressures generated by the plate motion in turn force the plate response) will be discussed. It will be demonstrated that the effects of convected fluid loading on sound radiation can be very significant.
