Perforations contribute to liquid redistribution in corrugated sheet packings. We focus on a simplified but relevant experimental configuration where a vertical perforated flat sheet is supplied with liquid on its front side. We examine how the perforations irrigate the back of the plate. We successively consider a single perforation, a spanwise row of perforations, and a staggered array of perforations. We quantify the liquid transfer through a single row of perforations and find that the transferred flow rate per unit perforation diameter varies linearly with the supply flow rate per unit width. We also analyze the spreading of the rivulets leaking from the perforations, their merging into a continuous wavy film, and the leveling of this film as it falls down the plate. The spreading and the merging exhibit a power-law behavior in agreement with theoretical models. The leveling exhibits exponential decay behavior.

“…The physics of the contact line region of a rivulet was first taken into account by Davis [13] and revisited from another point of view by Shetty and Cerro [14]. However, a literature covering the topic of modeling the flow of a spreading rivulet is still limited to various CFD methods (e.g.…”

Rivulet type flow is of great importance in many engineering areas including the packed columns design or heat exchangers calculations. We concentrate on the case of a rivulet flowing in the azimuthal direction from top to bottom of a large horizontal cylinder. A direct numerical simulation of the problem is compared to simplified solutions of the Navier-Stokes equations for the cases of a rivulet with (i) constant contact angle and varying width, (ii) constant width and varying contact angle, and (iii) varying both contact angle and width. Such comparison sheds light on the applicability of simplified models for a solution of real-life problems.

“…The effect of liquid viscosity and surface tension on the width of the rivulet was the main point analyzed by Nicolaiewsky et al [2]. Cerro and his coworkers [3][4][5][6][7] did a lot of experiments and numerical simulation of liquid film over different solid surfaces, and the effect of liquid properties and geometrical parameters of solid material were discussed. Although the published papers gave numerous experimental results and prediction correlations, the gas phase was dismissed.…”

Liquid film flow is very important in many industrial applications. However, there are few reports about its characteristics on structured packings. Therefore, in this paper, liquid film phenomena were investigated experimentally to exploit new approaches for intensifying the performance of the structured packings. All experiments were performed at room temperature. Water and air were the working fluids. The effect of counter current gas phase on the liquid film was taken into consideration. A high speed camera, a non-intrusive measurement technique, was used. It is shown that both liquid and gas phases have strong effects on film characteristics. In the present work, liquid film width increased by 57% because of increasing liquid flow rate, while it decreased by 25% resulting from the counter current gas phase.
