摘　　要：利用RNG k-ε两方程紊流模型和简化的多相流Mixture模型,模拟了单鳃片分离鳃装置有进出流时的水沙两相流流场.经分析表明,进出流的设置未破坏分离鳃装置中存在的垂向和横向两种异重流,不影响水沙分离效率,但泥沙大量淤积在分离鳃底部,未能及时有效地排出.In this paper, the improved RNGk-ε Two-equation Model and the muhiphase Mixture Model are used to simulate 3D solid-liquid two-phase flow in the flow of pass in and out the single gill-piece separation device. The results indicates that in-and-out setting of the flow in separation gills device does no damage to the different heavy flow existing in the vertical and horizontal direction, nor affect the water sand separation efficiency, but the sediment deposits in the bottom of the sepa- ration gills, failing to eliminate timely and effectively.
