高含沙分层流的试验研究

Experimental Study on Stratified Flow of Hyperconcentrated Fluid

高含沙水流进入低含沙量河流中时,往往形成比较稳定的分层流。通过水槽试验研究了泥浆流同向分层流的深度比,界面剪力在分层流中的作用,闸门开启引起的双向分层流的速度,以及各种分层流的稳定性.

By means of flume experiment and theoretical analysis, the flow depths and ratio of the depths of two-layer parallel stratified flow of non-Newtonian fluid, the stratified mud flow initiated by drag force of the upper layer high speed water flow on the interface, the reciprocal water mud stratified flow resulting froni opening of lock, and the stability of interface for non-Newtonian stratified flows are discussed in this paper.
