Tomographische Untersuchung der Fluiddynamik viskoser Systeme in Packungskolonnen

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.
