摘要参考试验用例的实验研究对于支持流固耦合问题数值模拟模型和耦合策略的发展具有重要意义。从实验角度来看，非定常流体流动与结构运动耦合的研究需要专门的实验设备和测量技术来获得精确的时间分辨结果。这一需求引发了目前设计和研究层流流固相互作用的二维参考试验案例的贡献。本文建立了一个新的高粘性流体实验装置，并采用粒子图像测速系统来测量周期流速场和结构挠度模式。最后定义并进行了参考实验。在雷诺数为170的情况下，对二维参考结构模型进行了扩展研究，得到了可重复性和准确性很高的结果，并编制了数据库。
AbstractExperimental studies on reference test cases are of capital importance to support the development of models and coupling strategies for numerical simulations on fluid-structure interaction problems. From the experimental view point, the study of the coupled unsteady fluid flow and structure motion requires specially adapted test rigs and measurement techniques to obtain accurate time-resolved results. This demand has triggered the present contribution to design and to study a two-dimensional reference test case on laminar fluid-structure interaction. A new experimental facility to be operated with high viscous fluids was build exclusively for the present study and a Particle Image Velocimetry system was adapted to measure both the periodical flow velocity field and the structure deflection modes. Finally the reference experiment was defined and performed. An extended investigation was conducted on the two-dimensional reference structure model at a Reynolds number of 170 and lead to very reproducible and accurate results compiled in a data base.
