水力旋流器内固相颗粒时均流场及脉动特性的研究

Researches on mean flow field and pulsation characteristics of solid particles in hydrocyclones.

利用一种新型的激光多普勒测速仪———粒子动态分析仪（ＰＤＡ），对水力旋流器中固相颗粒的时均流速、绝对湍流度、相对湍流度等流动参数进行了实测研究，给出了更全面的关于水力旋流器内固相颗粒流速分布的信息，并探讨了湍流脉动对水力旋流器分离过程的影响。

オhe mean velocity,absolute turbulence,relative turbulence of solid particles in hydrocyclones were measured by using particle dynamic analyser,a new type Doppler tachometer.A complete information of velocity distribution of solid particles in hydrocyclones was given,and an approach was made of the influence of turbulence and pulsation of the separation process.
