Experimental Study of Flooding in Vertical Narrow Rectangular channels
In this paper, counter-current gas—liquid two-phase flow and onset of flooding in vertical narrow rectangular channels were studied. The onset of flooding in vertical narrow rectangular channels was investigated by the condition at which the liquid on the channel wall begins to move partially above the liquid injection section. In order to study the flow pattern, during counter-current flow and determine conditions associated with the onset of flooding, the flow pattern and pressure drop were investigated by visual experiments. In addition, the flooding phenomena in vertical narrow rectangular channels were compared with that in conventional channels. The results show that the flow characteristics and the tendency of pressure drop in vertical narrow rectangular channels were similarly with the conventional channels. However, the maximum of pressure drop appeared at the completed carrying up of flooding in vertical narrow rectangular channels, and it appeared at the onset of flooding in conventional channels.
