A method for the simulation of flow induced tube and tube bundle vibrations is developed. Before flow around rigid bodies is simulated, to find suitable models for turbulence and the transition from laminar to turbulent. In the case of the single cylinder, the experimental data used to evaluate the simulation results are taken from literature. In the case of the tube sheet flow in heat exchangers, the velocity distribution in tube bundles made of glass are measured with the Laser Doppler Anemometry method. After formulating the model for the structure and checking it with analytical solutions, the coupled fluid structure method is applied to test cases from literature: first on flow induced vibration of a single cylinder, then on tube bundle vibrations.
