Computation of Acoustic Power, Vibration Response and Acoustic Pressures of Fluid-Filled Pipes.

Abstract

The time-harmonic excitation is either an interior point source of sound or a mechanical point force located on the pipe's surface. The acoustic power radiated into the exterior fluid, the vibration response of the pipe's wall, and the pressures in the exterior and interior fluids are computed by a simple integration scheme. Numerical results are presented for the case of a water-filled steel pipe that is surrounded by air.
