| 摘 要： | 采用均匀试验设计理论对鳃片倾斜角α与β进行数值模拟方案的设计,通过采用Fluent软件中的欧拉模型,以鳃片3上表面的泥沙速度作为考核指标,对不同鳃片倾斜角下的分离鳃速度流场进行模拟。运用投影寻踪回归分析法(PPR)对数值计算结果进行了分析,得出鳃片β倾斜角对分离鳃水沙分离效果影响是最大的,其次是鳃片α倾斜角的影响;当鳃片倾斜角的组合为α=60°与β=45°时,分离鳃中的速度流场有利于水沙的快速分离且水沙分离效果最佳。

| Abstract: | The scheme design of numerical simulation on tilt angle Aand tilt angle Bof gill2piece applied the uniform experimental
design theory. With the sediment velocity on the upper surface of gill 2piece 3 as the evaluation index, velocity flow field was sim2
ulated under different tilt angles of gill2piece through the adoption of Eulerian model provided by the Fluent software. The pro2
jection pursuit regression (PPR) was used to analyze the numerical simulation results. The results showed that the influence of
angle B on the effect of water 2sediment separation in the gill 2piece separation device is the highest, followed by the tilt angle A.
The velocity field of gill 2piece separation device is beneficial to increase water 2 sediment separation and the effect of water 2sedi 2
ment separation is the best under the combination of A = 60b and B = 45b. |
