| 摘 要： | 分别利用加单排鳃片和加双排鳃片垂向异重流式水沙分离鳃模型在含沙浓度为8%,10%,12%,15%,18%,20%的水中进行泥沙沉降的对比试验.通过试验对比分析,证明两种不同鳃片布置方式的垂向异重流式水沙分离鳃中的泥沙沉降速度规律基本一致,由加速下沉和减速下沉两个阶段组成,且两阶段历时基本相同.两种鳃片布置方式的分离鳃中水沙分离效果基本相当.

| Abstract: | Use the single-row gill-piece model of the vertical-component density flow water-sediment separation device and the double-row gill-piece model of the vertical-component density flow water-sediment separation device to do the comparative trial of different concentrations of sand(sediment concentration of 8%,10%,12%,15%,18%,20%).Through experiment contrastive analysis,proved that the silt settling rate rule of the two different gill-pieces arrangement is basically the same.The water-sand separation effect in... |
