本文提出了一个水力旋流器中流态的简化数学模型，该模型是以粒子相互作用原理和基本的流体运动学原理为基础的。在给矿浓度低和高时，也就是说从只有清水给入运转到沉砂完全堵塞时为止，得到的半经验化数学模型都精确地（51％的绝对误差）模拟了水力旋流器（小型实验室型）的流量特性（给矿）．
This paper presents a simplified mathematical model of the flow regime in hydrocyclones that is based on the principle of particle interaction and the basic fluid kinematics. The semi-empirical mathematical models obtained accurately and precisely (51% absolute error) simulate the hydrocyclone Small laboratory type) flow characteristics (to mine).
