ABSTRACT

An attempt has been made in this work to experimentally investigate the water split behavior of hydrocyclones for extracting the relevant features that are characteristic of hydrocyclone design conditions only. The experimental findings demonstrated that at high feed flowrates, the water split of the hydrocyclone attains a consistent value, referred to here as the stable split value, because of a fully developed and steady vortical flow through the hydrocyclone. These stable split values were shown to be characteristic of the hydrocyclone design conditions. An empirical model developed in the study considering the key hydrocyclone design variables could predict the stable split values with a validation R² of 0.98 and 0.96 for the training and testing data, respectively. It is believed that such a design-dependent parametric representation of the water split behavior can be significantly useful for hydrocyclone design comparison and selection which has not been reported in the literature so far.

摘要

本工作尝试通过实验研究水力旋流器的水分解行为，以提取仅作为水力旋流器设计条件特征的相关特征。实验结果表明，在高进料流量下，水力旋流器的水分流达到一致的值，这里称为稳定分流值，因为通过水力旋流器的涡流充分发展且稳定。这些稳定的分流值被证明是水力旋流器设计条件的特征。研究中开发的经验模型考虑了关键的水力旋流器设计变量，可以通过验证 R ^{2来预测稳定的分裂值}训练数据和测试数据分别为 0.98 和 0.96。据信，水分离行为的这种依赖于设计的参数表示对于水力旋流器设计比较和选择非常有用，迄今为止文献中尚未报道。
