Fully Decoupled Time-Marching Schemes for Incompressible Fluid/Thin-Walled Structure Interaction
Date:
Conference Talk at 12th U.S. National Congress on Computational Mechanics (USNCCM12), Raleigh, North Carolina, USA
Conference presentation on fully decoupled time-marching schemes for incompressible fluid and thin-walled structure interaction. The schemes combine a projection method in the fluid with a Robin-Neumann treatment of the interface coupling, so that the fluid velocity, the fluid pressure, and the structure displacement are computed sequentially, each only once per time step. The talk discussed energy-based stability properties of the resulting schemes with respect to the added-mass effect and illustrated their accuracy and efficiency on numerical benchmarks.
The fully decoupled scheme introduced in this talk was later developed into the following journal papers: Comptes Rendus Mathématique (2013) · Journal of Computational Physics (2015)
