摘要：

The paper is concerned with two main aspects, which should be considered when large-eddy simulation (LES) is married to fluid-structure interaction (FSI). First, the influence of moving grids leading to temporally varying filter widths and thus additional commutation errors on the quality of the predicted results is thoroughly investigated. Second, a new partitioned coupling method based on the predictor-corrector scheme often used for LES is evaluated. A strongly coupled but nevertheless still explicit time-stepping algorithm results, which is very efficient in the LES-FSI context. This new scheme is evaluated in detail based simulations around elastically supported cylindrical structures and a swiveling flat plate.
