水力旋流器固体颗粒运动行为的分析

通过对旋流器内固体颗粒的受力分析,提出固体颗粒精确运动轨迹结构是由确定性的径向力、轴向力以及不确定性的随机力所决定,并对固体颗粒存在的随机因素进行了分析.在此基础上,分析了固体颗粒与液体的跟随性,认为在强湍流情况下,颗粒除在径向方向的运动有别于液体介质外,在轴向与切向也存在差异,且这种差异与颗粒粒度大小、密度、流体性质以及湍流强度有关.

Analysis on the Particle Motion Behaviour within Hydrocyclones

According with analyzing the forces acting on a particle ,put forward the particle accurate motion trajectory which is determined by the certainty axial and radial force , as well as the uncertainty stochastic forces . Based on the above factors, the following motion characteristics between the solid and the liquid was analyzed, the following property of solid-liquid exists in all radial, axial and tangential directions. Under strong turbulent flow condition the property in three direction is different , and it relates with the particle granularity and density , as well as the fluid property and the turbulent intension.
