Descrição

A fixed cylindrical circular cavity and a cylindrical circular column of fluid of infinite length submerged in a homogeneous fluid medium, and subjected to a pressure point source, for which closed form solutions are known, are used to assess the performance of constant, linear and quadratic boundary elements in the analysis of acoustic scattering. http://www.sciencedirect.com/science/article/B6V1P-43CB9CN-3/1/002dea35b84a8e01ba5193ee8925f4e6
