Abstract :

[en] 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. © 2019, Wiley-VCH Verlag. All rights reserved.
