【摘要】 本文介绍了在小型循环水槽中进行的两维翼水致振荡显示实验。流态显示以ＰＩＶ技术为主，辅以染料示踪技术。试验说明了ＰＩＶ技术可以应用于被动振动非定常复杂流场的测量中，并对两维翼流体旋涡诱发振动响应进行了分析。更多还原

【Abstract】 The experiment displaying the water-induced vibration of a two-dimensional wing is carriedout in a small cireulating water channel. The PIV technique and auxiliary dye-tracer technique are used todisplay the flow field. The experiment shows that the PIV technique can be utilized to measure the unsteadycomplex flow of passive vibration, and to analyse the vortex-induced vibration.更多还原
