Numerical Benchmarking of fluid-structure Interaction between an elastic Object and laminar incompressible Flow
Abstract
We describe new benchmark settings for the rigorous evaluation of different methods for fluid-structure interaction problems. The configurations consist of laminar imcompressible channel flow around an elastic object which results in self-induced oscillations of the structure. Moreover, characteristic flow quantities and corresponding plots are provided for a quantitative comparison.
Introduction
The main purpose of this benchmark proposal is to
describe specific configurations which shall help in future to test
and to compare different numerical methods and code implementations
for the fluid-structure interaction (FSI) problem. In particular, the
various coupling mechanisms, ranging from partitioned, weakly coupled
approaches to fully coupled, monolithic schemes are of high interest.
Moreover, it shall be possible to examine the quality of different
discretization schemes (FEM, FV, FD, LBM, resp., beam, shell, volume
elements), and the robustness and numerical efficiency of the
integrated solver components shall be a further aspect. This new
benchmark is based on the older successful
