Dynamic interaction for structures in fluid flows

The project deals with modelling and analytical studies of mechanical systems where an elastic structure interacts with a fluid flow. Most aeroelastic models today are either too complex for analytical studies or contain assumptions that only holds for very few applied aeroelastic systems. The modelling part of this project concentrates on deriving aeroelastic models which can be used for analytical studies of a larger variety of systems. The models are typically nonlinear thus the analytical studies that follows the modelling apply methods from nonlinear dynamics. The aim of particular studies in the project is to explain aeroelastic phenomena which can be observed in experiments. Some of these systems are rotating disks in a fluid, articulated plates in a uniform flow and a squared prism in uniform flow.
