This paper presents the results of a comprehensive experimental study performed with a Sulzer high-capacity structured packing of a larger specific area, which provided a basis for validation of the Delft model. Purely geometry-based adaptations were made to the Delft model, to account properly for the effect of short smooth bends on both ends of each corrugated sheet, which, in turn, seemed to be beneficial for capacity without adversely affecting the efficiency. Comparisons indicate fairly good agreement with experiments as well as with the predictions of an in-house empirical model contained in Sulzer's software package, Sulpak.
