Up to now the prediction of separation efficiency for disk stack separators is largely based on the concept of equivalent clarification area, short Σ‐theory, firstly published in 1949. An improved analytical model with a closed‐form solution is presented in which the assumptions of uniform flow and unhindered solids transport are dropped. The contributions of distributor and solids holding space to the total separation efficiency are considered. The model is validated by comprehensive experiments with different geometry parameters and particle systems. The results are presented in a universal form for a combination of dimensionless numbers.

表征磁盘堆栈分离器效率的分析模型

到目前为止，对磁盘堆分离器分离效率的预测主要基于等效澄清区的概念，即简短的Σ理论，于1949年首次发布。提出了一种改进的带有封闭形式解决方案的分析模型，其中的假设为均匀的流动和不受阻碍的固体输送下降。考虑分配器和固体容纳空间对总分离效率的贡献。通过使用不同几何参数和粒子系统的综合实验验证了该模型。结果以无格式数的组合的通用形式表示。
