摘　　要：通过设定两相流分离鳃不同泥沙下沉通道宽度,对含沙水流进行泥沙沉降试验。结果表明,分离鳃的最小泥沙下沉通道宽度为1mm,否则泥沙将会发生淤堵。在通道宽度在2～5mm时,随着通道宽度的增加,泥沙沉速加快;当通道宽度>5mm时,随着通道宽度的增加,泥沙沉速变化不大。Abstract： The sediment deposition experiment was conducted in vertical-component density mixture flow separation gill with different sediment settling access width. The experimental data show that the minimum settling access width is 1 ram, or the sediment will be silted up. When access width is 2-5 ram,the sediment settling increases with the increase of access width;When access width is 〉5mm, the settling velocity of sediment is steady with the increase of access width.
