Abstract

Algorithms for Fluid-Structure Coupling techniques are investigated in the time domain. The accurate pediction of the interaction requires consistency of the interface boundary conditions with the time levels of integration of the fluid and the structure equations. If staggered algorithms are used, the time delay causes non-physical energy dissipation in the system which modifies the calculated aeroelastic behaviour. In order to be compatible, the equations must be integrated simultaneously and implicitly. These techniques are tested on a standard aeroelastic airfoil problem, and then applied to the direct coupling of an assembly of 20 compressor blades performing torsional vibrations.
