The thesis deals with numerical simulation of flow induced sound. A partitioned approach for the coupled simulation of sound generating flows and vibrating structures is presented. On the fluid side, the Lattice-Boltzmann-Method is used, while the dynamics of the structure are represented by the Finite Element Method. A framework algorithm controls the exchange of all necessary data, thus enabling the simulation of the interaction between flow and structure. To validate the method, simulations of simple models were performed. Furthermore, an industrial example showing similar effects is demonstrated.
