摘要
分析了水力旋流器内固体颗粒所受到的随机作用力湍流脉动的影响,认为湍流频率的变化对颗粒与流体间的跟随性有显著的影响。在此基础上对不同粒径的固体颗粒的运动轨迹进行了数值模拟,进一步形象直观地描述了湍流对固体颗粒运动行为的影响。
The impact of solid particles inside the hydrocyclone by random forces of turbulent fluctuation is analyzed, and it is presumed that a significant impact occurs on the relative motion between the particles and the fluid when the turbulent fluctuation changing. On this basis, the trajectories of the solid particles with different sizes are numerically simulated, and further visual impact on the movement behavior of solid particles by turbulence is described as well.
