摘　　要：在进料浓度较低时,固相颗粒之间距离较大,相互之间的作用以及影响极微,颗粒的分离可以通过对其施加一个外力,将其往器壁方向推,这样就完成了固-液-液三相的分离。这个外即惯性离心力的大小很容易得到,但颗粒所受流体介质阻力则很难得到。文章文通过研究对对旋流器内部固相颗粒进行了受力分析并从理论上对细颗粒易受参数影响的原因进行了阐述。At low concentrations, the individual particles are on average so far arpart that they do not affect each other in their movement through the fluid. Particle separation can be achieved by putting a force on the particles which will move toward a surface where they will separate. The magnitude of the force can usually be easily expressed but the opposing particle motion, the drag force, is more difficult to establish. In the paper, The reason why particles of smaller-diameter more sensitive to the changes of parameters was explained through a force balance analysis.
