Flutter valv.xlsx

Flutter on cardiac valves was studied. An analytical methodology was created to evaluate the critical speed of fluid for the onset of flutter. Also an experimental test was made to evaluate the critical speed on a test bench using a high speed camera on various flows. Dimensioness analysis was done to compare the results.<br>本研究针对心脏瓣膜颤振（Flutter）展开相关研究。首先，构建了一套分析方法，用于评估颤振发生所需的流体临界速度；其次，搭建试验台开展实验测试，针对不同流动工况采用高速摄影机采集数据以测定临界速度；最后，通过无量纲分析对所得结果进行对比验证。
