Abstract

We introduce a hybrid analytical-numerical approach to modeling the acoustic field radiated by a submerged structure of a cylindrical outer shape but without any limitations on the geometrical and/or physical complexity of the internal composition. The approach relies on the FEM methodology in modeling the structural dynamics but utilizes the analytical response-functions-based ideology for the fluid domain, providing the advantage of being able to handle complex geometries that are outside of the capabilities of the traditional analytical or semi-analytical approaches, but at the same time possessing the computational efficiency that is higher than common FEM fluid-structure interaction codes. The capabilities of the approach are demonstrated on a typical configuration of industrial interest
