GRK 432:  Interaction of Structures and Fluids

• Subject Area: Mechanics and Constructive Mechanical Engineering
• Term: from 1998 to 2007
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 272369

Objective of the research training group is to scientifically examine forces on and displacements of systems of deformable solids and fluids, taking into consideration the mechanical interaction phenomena in the boundary surfaces of the system components. Energy exchange between solids and fluids can be of major importance for the overall behavior of the system. Examples are vibration of tall and slender structures under wind loading, flutter of aircraft wings, forces on coastal or off-shore structures resulting from wave impact, and wave propagation in the liquid matter conducted by a pipeline.The research program of the research training group is aimed at developingmechanical models and numerical solution techniques for fluid-structure interaction problems and at studying thoroughly the phenomena observed in fluid-structure systems. Co-operation of the departments of Civil Engineering, Mechanical Engineering, Mathematics and Computer Science guarantees effective, systematic, and interdisciplinary research on current problems relevant on a technological background.It has been common practice for standard problems to describe eachsystem component of a fluid-structure system in a separate way. Thisusually has been done by employing static or dynamic coefficientsaveraged over the entire boundary surface. However, this model does not describe the system behavior correctly once there is high energytransfer associated with the movement of the boundary surfaces betweenthe two components. In this case it often becomes necessary to examinethe behavior of the combined fluid-structure system.
