| 1 | Turbulence,suspension and downstream fining over a sand-gravel mixture bed显示文摘斜槽实验被执行在沙石子混合床上在单向性的流动条件下面在谷物尺寸的暂停和分离上学习骚乱和它的影响。有变化的液体速度的部件用 3-D 垂直地被测量微声学的 Doppler 速度计(副词) 。为速度和沉积暂停的理论模型基于混合在沙石子混合床上在流动由于沉积暂停包括骚乱的抑制效果的长度的概念被开发了。床下游的谷物尺寸的分离的统计分析用问题的无指导的学习或聚类的原则被执行了。探索数据分析建议沿着流有有石子,沙石子和沙材料的选择免职的沉积尺寸的进步下游的 fining,它可以被分割进三个区域例如,在上游,过渡并且下游分别地。这贡献是相关的在通过风景控制沉积流动理解古老的河,在河形式的床材料特性,排序的过程和它的角色的方向。 | K.GHOSHAL Rahul MAZUMDER C.CHAKRABORTY B.S.MAZUMDER | 2013 | International Journal of Sediment Research2013，28，2： | 2 |
| 2 | VELOCITY AND SUSPENSION CONCENTRATION IN SEDIMENT-MIXED FLUID显示文摘The present paper is focussed on the effects of viscous and turbulent shear stresses on both vertical velocity and concentration distributions in large suspension of sands. When the flow carries large amount of sediments in suspension, the properties of fluid mixture are changed in terms of modified viscosity, density and fall velocity, and hence the flow characteristics. Theoretical models have been developed for both velocity and concentration profiles, taking into account the viscous and turbulent shear stresses, which are the function of volumetric concentration. Comparison of theoretical models with experimental data reveals that (i) the modified velocity and concentration profiles agree well with the observed data for high suspension, (ii) the higher the sediment suspension, the smaller the von-Karman constant, and (iii) sediment diffusion coefficient is less than momentum diffusion coefficient for fine sands in suspension. | B.S.MAZUMDER K.GHOSHAL | 2002 | International Journal of Sediment Research2002，17，3： | 1 |
