| 摘 要： | 粒子图像测速（PIV）是一种快速全流场测量方法。为克服PIV设备昂贵和操作复杂等缺点，文中介绍一种新的简化PIV方法。它是根据PIV测速原理，并利用现有的连续抓图软件，CAD和Origin等绘图软件对示踪粒子进行捕捉及图像处理，并将其应用于水底浮帘截留促淤装置的实验中，成功获得了浮帘后方回流区的瞬时流场分布图。

| Abstract: | The particle image velocimetry(PIV)is a fast and whole current field measur- ing method,and a simplified PIV method is developed to overcome the PIV shortcom- ings such as expensive equipment and complicated operations.The simplified method is based on the velocity measuring principle of PIV and uses available softwares of continu- ous catching image,CAD and Origin to catch the tracer particles and make the image processing.In this paper,the simplified PIV method is applied to an experimental de- vice to use an underwater floating curtain for sediment retention and deposition promo- tion on the channel bed,and the distributions of instantaneous current field in the lee of underwater floating curtain are successfully obtained. |
