摘要： 田新亮研究小组提出了一种简称为“软尾减阻”的新型流动控制方法，即通过在钝体后侧构造柔性封闭体来调节其所受流体载荷及周围流动形态．相比于传统流动控制方法，该方法无需改变控制对象的结构，具有良好的工程应用前景．同时，“软尾减阻”引出了一种新的“流-固-流”耦合问题，亟待进一步研究．

Abstract: Tian Xinliang’s group proposed a novel flow control method called "Flexible coating reduces drag" (FCRD) with a flexible enclosure constructed behind the bluff body to adjust the fluid forces received and the flow pattern around it. Compared with the traditional flow control methods, FCRD does not change the structure of the control object and thus has a positive engineering application prospect. Besides, FCRD brings out a new "fluid-structure-fluid" interaction problem, which needs further investigation.
Key words: fluid structure interaction, drag reduction, flow control, soap film
