Abstract
A framework for fully coupled numerical simulation of fluid flow, structural deformation, and acoustics is presented. The methodology involves an implicit partitioned approach for fluid-structure interaction, a viscous-acoustic splitting technique for flow acoustics, and corresponding coupling schemes. All components are designed for the use on parallel high-performance computers. Special emphasis is given to the use of geometric multi-grid techniques in order to increase the efficiency of the numerical simulations. Results for several test cases illustrate the capabilities of the approaches considered.
