Abstract

The boundary-element method is applied to solve for the radiation or scattering from multiple cylinders having given surface normal velocity distributions. The axisymmetric case is considered where all cylinders have the same axis of symmetry with an arbitrary surface velocity field. The algorithm is applied to solve for scattering from rigid cylinders with hemispherical endcaps. Numerical results are presented for different two- or three-cylinder configurations with a plane wave incident from various directions. The dependence of the scattered field on the distance between two identical cylinders is examined as well as scattering from one large and one small cylinder.
