Influence of orifice type and wetting properties on bubble formation at bubble column reactors

摘要

We show a direct numerical simulation (DNS), which is capable of describing immiscible two-phase flow including surface tension and the dynamics of partial wetting. Our investigation focuses on the initial bubble formation process at the inlet and analyzes the dynamics of the bubble detachment. It is shown, how orifice geometry and wetting properties influence size and surface of the bubble. This approach has a high potential for liquid liquid reactions and high pressure gas-liquid reactions.
