Abstract
The spreading of liquid in a packed column can be simulated by a dispersive mechanism using the Dutkai and Ruckenstein boundary conditions at the wall. The model has been extensively tested by collecting results on a 600 mm diameter column over a wide range of packed depths and liquid loadings. It was found that a wall distributor was the most suitable in determining the model parameters. There is a considerable variation between the model and experimental results due to an altered rivulet pattern on changing the liquid loading. However the Dutkai and Ruckenstein model does provide the principal features of radial and axial liquid dispersion.
