Abstract盐度等因素对泥沙絮凝沉降的影响是本文的研究目的.考虑了泥沙颗粒在水中的多体相互作用, 以及颗粒间的XDLVO势.分析了盐度、泥沙浓度、Hamaker常数、水合作用对泥沙絮凝沉降的影响.获得的泥沙絮凝沉降速度的拟合公式与计算和试验相符, 对于工程实际有重要参考意义
Other AbstractThe effects of salinity and other factors on flocculation settling are investigated in this paper. The many-body hydrodynamic interactions and XDLVO potential between sediment particles are taken into consideration. The effects of salinity, sediment concentration, Hamaker constant and hydration on settling speed are analyzed. The obtained fitting formula for flocculation settling speed accords with computational and experimental results and is of referential importance.
