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.

土木及环境工程系 克拉克森大学将购买多相流水槽 研究将致力于支持以下内容 研究内容：（1）模拟冰的同时输运 河流泥沙输移特性; 大固含率下的固-液输运;（3）水 波浪与冰的相互作用;（4）质量输运 近浮力沉积物的关系;（5） 污染物（油）的表面迁移及其混合 水柱。 用于多相流研究的水槽 由工作长度为40 '的矩形通道组成 （12.2米）长，横截面宽度和高度为 1'-6 "（0.457 m）× 2 '（0.610 m）。 水槽是 设计用于同时循环水和两个 分离固相。 第一个阶段是浮力， 其他无浮力。 水和每种固体的流速 相位可以独立控制。 河床 可以在0度和+6度的斜率之间变化。 专门 将提供设计的排放储存设施， 对不混溶的表面铺展进行研究 液体，如水中的油。 这些研究的结果 将应用于民用基础设施， 行业
