Flow-Induced Vibrations – Institute of Turbomachinery and Fluid Dynamics

Flow-Induced Vibrations

The lecture provides an introduction to the aeroelasticity of blunt bodies. Emphasis is placed on eddy-induced and motion-induced vibrations due to strong flow separation and the resulting aeroelastic problems in the fields of marine engineering, offshore wind energy, aerospace and civil engineering. You will learn the fundamentals of the interactions that occur between the vibrating structure and the flow. Actual real-world examples are used to address dynamic aeroelastic phenomena, showing the limitations of applying potential theory and deriving and applying advanced theoretical models. In an experiment in the high-pressure wind tunnel in Göttingen, the fundamentals learned will be applied to a forced-excited wind tunnel model. At the end of the course you will be able to recognize, model and analyze the different types of vibrations.
