Engineering Research Equipment: Flume for Multiphase Flow

克拉克森大学土木工程与环境工程系将购买一个用于多相流研究的水槽，该水槽将致力于支持以下研究：(1)模拟的脆性冰和河流中泥沙的同时输送；(2)大固相分数下的固液输送特性；(3)水波和冰块的相互作用；(4)近浮力沉积物的质量迁移关系；(5)污染物(油)的表面迁移及其在水柱中的混合。用于多相流研究的水槽由一条工作长度为40‘(12.2米)的矩形渠道组成，横截面宽度和高度分别为1’-6“(0.457米)和2‘(0.610米)。该水槽被设计为同时循环水和两个独立的固体相。一种是有浮力的，另一种是非浮力的。水和每一固相的流速可以独立控制。渠道的河床可以在0度和+6度的坡度之间变化。将提供特别设计的排放储存设施，以便研究不相容液体(如水中的油)的表面扩散。这些研究成果将在民用基础设施和工业中得到应用。

The Department of Civil and Environmental Engineering at Clarkson University will purchase a flume for multiphase flow studies which will be dedicated to support the following studies: (1) simultaneous transport of a simulated frazil ice and sediment in rivers; (2) conveyance characteristics of solid-liquid transport at large solid fractions; (3) water wave and ice fragment interaction; (4) mass transport relationships for nearly buoyant sediments; and (5) the surface transport of contaminants (oil) and their mixing into the water column. The Flume for multiphase flow studies consists of a rectangular channel with a working length of 40' (12.2m) in length having a cross section width and height of 1'-6" (0.457m) by 2' (0.610m) respectively. The flume is designed to simultaneously recirculate water and two separate solid phase. One phase is to be buoyant and the other non buoyant. The flow rate of water and each solid phase can be independently controlled. The bed of the channel can be varied between slopes of 0 and +6 degrees. Specially designed discharge storage facilities will be provided enable studies to be conducted on the surface spreading of immiscible fluids such as oil in water. The results of these studies will have application in the civil infrastructure and industry.
