粘性细颗粒泥沙静水絮凝沉降生长的计算机模拟

Computer simulation of flocculation growth for cohesive sediment in still water

利用分形生长模型对粘性细颗粒泥沙的絮凝沉降过程进行了计算机模拟,在扩散受限的絮团聚集模型(DLCA模型)的基础上,初步研究了粘性细颗粒泥沙的絮凝沉降分形生长过程,并对最终的絮凝体进行了图像处理,得到了分形维数和颗粒浓度的关系。

Using the fractal concept, the growth of cohesive sediment was simulated by computer. The fractal growth and flocculation-sedimentation process of cohesive sediment was researched by Diffusion Limited Cluster Aggregation （DLCA） model. The fractal structure was analyzed by graphic technology, and the variation relationship between fractal dimension and sediment volume fraction was finally achieved.
