| 摘 要： | 钝体是工程中一种常见结构，流体绕过钝体时产生的旋涡脱落易诱发结构振动，进而导致结构破坏．钝体后安装分隔板是一种典型的被动控制技术，分隔板推迟钝体尾流区剪切层之间的相互作用，进而有效改变钝体后旋涡脱落及尾迹特性，延长结构寿命，并且可以利用钝体一分隔板结构进行能量收集．本文全面回顾了利用分隔板进行流动控制和能量收集的研究及... |

| Abstract: | Bluff bodies are widely used in engineering.The vortex shedding behind bluff bodies can induce vibration and thereby cause structural damage.Adding a splitter plate downstream of a bluff body is an efficient passive control technique.The interaction between shear layers is postponed by the splitter plate.Then vortex shedding and near wake interaction of the bluff body are controlled efficiently,and then the service life of structure will be extended.The body-plate configuration can also be used for energy h... |
| Keywords: | splitter plate bluff body vortex shedding flow control energy harvesting |
