| 摘 要： | 针对人工鱼礁周围复杂的流场效应进行的研究已经较为成熟,然而对于不同开口比的人工鱼礁对流场效应影响的系统评价并未提出。针对一组不同开口比的人工鱼礁进行数值模拟,提出关于人工鱼礁流场效应影响的评价体系,并对不同开口比的人工鱼礁的流场效应进行全面评价。评价结果认为开口单体人工鱼礁优于不开口的实心鱼礁,但开口不应过大,在单孔鱼礁情形下,开口比为0.04时流场效应最优。

Evaluation on Effect of Artificial Reef Opening Rate on Flow Field Effects |
| |
| Abstract: | The research on complex flow field effect around artificial reef is mature,however,the evaluation of effect of artificial reef with different opening rates on convective field effects was not proposed.Numerical simulation of artificial reef specimens for a set of different openings was carried out,the evaluation system of effect of artificial reef flow field effect was put forward,and the flow field effect of numerical simulation results was evaluated comprehensively.It showed that the opening artificial reef was superior to the non-opening reef,and the opening should not be too large.In the case of single-aperture artificial reef,the flow field effect was optimal when the opening ratio was 0.04. |
