Design and Evaluation of Staggered Partitioned Procedures for Fluid-Structure Interaction Simulations

Résumé

Numerical simulations of unsteady flows past a flexible structure require the simultaneous solution of structural dynamics and of fluid dynamics on deformable dynamic meshes. We present here an evaluation method of staggered partitioned procedures for time-integrating these focus coupled problems. This method is based on an estimation of the energy that is numerically created at the fluid/structure interface because of staggering. Simplifying assumptions make this estimation easy for a wide family of mixed explicit/implicit or implicit/implicit, synchronous or asynchronous procedures. Insights gained from this evaluation method are confirmed with the analysis of numerical results for the flutter of a flat panel in supersonic airstreams in two and three dimensions and for the transient aeroelastic response of an AGARD 445.6 wing in the transonic regime.
