Near-Field Calculations For A Rigid Spheroid With An Arbitrary Incident Acoustic Field, John P. Barton, Nicholas L. Wolff, Haifeng Zhang, Constantine Tarawneh

Mechanical Engineering Faculty Publications and Presentations

A general spheroidal coordinate separation-of-variables solution is developed for the determination of the acoustic pressure distribution near the surface of a rigid spheroid for a monofrequency incident acoustic field of arbitrary character. Calculations are presented, for both the prolate and oblate geometries, demonstrating the effects of incident field orientation and character (plane-wave, spherical wave, cylindrical wave, and focused beam) on the resultant acoustic pressure distribution.
