TITLE : 2D CHANNEL FLOW IN A TRAY COLUMN (LIBRARY CASE W775)

BY : CHAM Consultancy Team

DETAILS :

• Liquid flows steadily along a tray from left to right, escaping over a weir.

• Air bubbles up through the tray, escaping freely to atmosphere.

• The task is to predict the thickness and the void fraction of the bubbly layer on the tray.

Pictures are as follows :

1. Grid (scale enlarged 5 times in y direction)
2. 1st-phase (vapour) velocity vectors
3. 2nd-phase (water) velocity vectors
4. Contours of pressure
5. Contours of 1st-phase (vapour) volume fraction
6. Contours of concentration in 1st phase (vapour)
7. Contours of concentration in 2nd phase (liquid)
