伴有滑动床的大颗粒水沙浆体浓度分布研究
Study on concentration distribution of coarse sand water slurry with sliding bed
摘要
Abstract
Calculation model of water and sediment concentration distribution above sliding bed is derived out based on two layers model,and further combined with the linear distribution characteristics of shear layer concentration.Concentration distribution and experimental data of other transport parameters varying with pipe angel are determined by the test of 1.71 mm coarse particles with high concentration.Comparison of concentration distribution between observation and values computed by author's model shows that the three layers concentration calculation model can predict the coarse particle concentration distribution above the sliding bed more accurately than the two layers concentration model.关键词
