人工鱼礁礁体模型阻力系数的实验研究
Research on Model Experiments of the Resistance Coefficient of Artificial Reefs
摘要
Abstract
In order to make the quantitative analysis between the resistance coefficient and the opening rate of the reef on different types of centre opening (circular, triangle, square), the hydraulic resistance coefficient of artificial reefs under different angles were studied through wind tunnel experiments. The ex periment results showed that the value of Cd decreased with the increase of projection opening rate (γty). When projection opening rates (γty) were the same and higher than 0. 1, the value of Cd decreased with the increase of permeability opening rate (γtt). The formula of the resistance coefficient was Cd --0. 861γtt + 0. 145γty+1. 268 (R2 =0. 729, P<0. 01) on different types of centre opening. The calculating result showed approximately coherent with the model test data of Hui style and Cube style reef, and the error was less than 8%. Thus, we can design a new artificial reef with good hydrodynamic characteristic by means of adjusting the opening rate.关键词
