Abstract
In this study, characteristics of liquid film flow and mass transfer were experimentally investigated in a downward annular flow system with two-phase flow of air and water. The liquid film thickness was evaluated by laser induced fluorescence, and the mass transfer was measured by the plaster dissolution method. The experiments were carried out in the vertical straight pipe flow with and without orifice at Reynolds numbers for liquid-film of 230, 470, 710 and 950, which were evaluated based on liquid film thickness and bulk velocity. The experimental results revealed that the mass transfer coefficient in the two-phase flow was higher than that in the single-phase flow at the same Reynolds number due to the influence thinner liquid film and boundary layer. The non-dimensional mass transfer coefficient behind the orifice in the two-phase flow showed a decrease in the peak value with decreasing liquid film Reynolds number, thought the distribution was similar to that of the single-phase flow.
