Abstract
The paper presents two different facets of the interaction of aerodynamic noise with a fuselage-shaped body. The first problem is the effect of scattering of an acoustic source by a body at rest. A numerical technique is presented which permits the computation of this scattering for frequencies of aeroacoustic interest. A parallel experiment is described which confirms the results of the computations. A numerical study of varying the geometry of the scattering is presented. The second problem is to simulate the effect of forward motion on the mean velocity and static pressure profiles in the wake of such a body with a jet exiting from it. Experimental results are presented and a similarity law is given. Directions for future research in this field are discussed.
