(Lisbon Symposia会议论文)流过细弹性结构的流体结构声学交互作用的实验研究

In the present paper the fluid-structure-acoustic interaction of a thin flexible structure in the wake of a wall-mounted square cylinder is investigated experimentally. The experiments are performed in an acoustics wind tunnel employing microphone measurements of the sound pressure level. Detailed flow measurements are carried out using laser-Doppler anemometry and 3D-hot-wire anemometry. The flow induced vibration of the flexible structure is measured with a laser scanning vibrometer. Experimental results characterizing the flow field, the structural vibration and the generated sound are presented.
