Kenics静态混合器的流体力学性能

HYDRODYNAMIC PERFORMANCE OF KENICS STATIC MIXER

用激光测速仪(LDV)测定了φ50mm Kenics静态混合器的流场、压力降和液滴平均直径。着重讨论了流量和混合单元数对轴向速度、切向速度和湍流强度的影响,并对静态混合器内液滴粉碎的机理进行了探讨。研究结果对消化吸收引进技术和合理地设计大型静态混合器具有参考价值。

The flow field,pressure drop and mean drop size in 50 mm Kenics static mixer have been measured using LDV. Effects on the axial and tangential component velocities and turbulent fluctuation by flowrate and number of mixing unit are discussed,and then the mechanism of the drop-breaking in the static mixer is explored. The results of this paper can be used for the scale-up of this kind of static mixer.
