The described test case FSI-PfS-1a is a part of a series of reference test cases designed to improve numerical FSI codes. A second test case FSI-PfS-2a is described in Kalmbach and Breuer (2013). The geometry is similar to the first one: A fixed rigid cylinder with a plate clamped behind it. However, this time a rear mass is added at the extremity of the flexible structure and the material (para-rubber) is less stiff. The flexible structure deforms in the second swiveling mode and the structure deflections are completely two-dimensional and larger.

Choice of test case

In the present study a slightly different configuration than in FSI-PfS-1 is considered. Nevertheless, both cases belong to the same series of investigations carried out in order to provide appropriate benchmark test cases for FSI.

Again the structural model consists of a fixed cylinder with a rubber tail (different material than before). Furthermore, in contrast to FSI-PfS-1 a rear mass is attached to the (para-)rubber plate. These modifications lead to stronger (completely two-dimensional) deflections and another swiveling mode of the structure. Again, strong emphasis is put on a precise description of the experimental measurements, a comprehensive discussion of the modeling in the numerical simulation (for the single field solutions as well as for the coupled problem) and the processing of the respective data to guarantee a reliable reproduction of the proposed test case with various suitable methods. A detailed description of the present test case including all details of the experimental investigations is published in Kalmbach and Breuer (2013).
