摘要
采用粒子图像测速(PIV)二维流场测速技术和水槽模拟试验研究了人工鱼礁的流场效应,对单体开口比分别为0、0.04、0.16、0.25的人工鱼礁在来流流速分别为67、112、180 mm/s时产生的流场效应进行分析。结果表明:单体人工鱼礁流场效应中,开口比和来流流速均对流场效应产生影响,开口比越小,来流流速越大,流场中的上升流流速和背涡流面积就越大。研究表明,影响流场效应的主要因素是开口比,来流流速的影响程度次之。
The flowing field of artificial reefs was studied in single cube artificial reefs with monomer cut-opening ratio of 0,0.04,0.16, and 0.25 at three different incoming velocities of 67, 112, and 180 mm/s by PIV （ particle image velocimetry） two-dimensional flow field measurements and water channel physical investigation. The results showed that the opening ratio and the incoming flowing velocities showed an influence on the flowing field of the sin- gle cube artificial reefs, with the more incoming flowing velocities at the less opening ratio in the artificial reefs and the higher upwelling average velocity at the larger areas of reverse vortex, indicating that the major factor influen- cing upwelling average velocity and area of reverse vortex was the opening ratio of the artificial reefs, followed by the incoming flowing velocity.
