用X射线层析成像技术研究了规整填料中的流体动力学。重点是设置在5和50 mPa s之间变化的液体粘度的影响。膜流是主要的流动模式,但也存在接触点液体模式,代表液体在相邻填料板之间的接触点处积聚。两种流型的滞留分数进行量化,并确定平均表面积与体积比。此外,结构填料的润湿比检查不同的粘度和液体负载。
Fluid dynamics in structured packings is investigated by X-ray tomography. The focus is set on the influence of liquid viscosity varied between 5 and 50 mPa s. Film flow is the dominant flow pattern, but there are also contact-point liquid patterns representing liquid accumulated at contact points between adjacent packing sheets. The holdup fractions of both flow patterns are quantified, and the average surface-to-volume ratio is determined. Furthermore, the wetting ratio of the structured packing is examined for different viscosities and liquid loads.
