Acoustic radiation pressure on a rigid cylinder: An analytical theory and experiments

Abstract

Simple and general analytical expressions are derived for the acoustic radiation force on a long rigid cyclinder with a small diameter, whose axis is perpendicular to the wave propagation. Results are expressed in terms of the time-averaged densities of kinetic and potential energies of the incident sound field. For the case of a standing-wave field, which was used in these experiments, the theoretical results agree well with the experimental observations.
