Abstract
A coupling scheme for the simulation of problems involving fluid-structure and fluid-structure-acoustic interactions is described. For the simulation of fluid-structure interactions an implicit coupling between the flow field and the mechanical structure is applied. In order to determine the acoustic radiation due to mechanical vibrations, a direct coupling between the mechanical structure and the acoustic field is employed. At the structure-acoustic interface non-matching grids are realized with mortar elements. The exchange of physical quantities between the structured mesh of the flow computation and the unstructured mesh of the structural computation is performed by MpCCI. Applications to the flow around an oscillating rigid body and the flow over a flexible plate are presented.
