“…It is of considerable importance to prevent the liquid film from break‐up in falling film reactors in order to ensure an efficient heat and mass transfer process 24–26. However, the liquid film in microchannels may not be complete by the presence of dry strips, patches, or spots, as revealed in Figures 3a–d.…”

In this article, flow pattern of liquid film and flooding phenomena of a falling film microreactor (FFMR) were investigated using high-speed CCD camera. Three flow regimes were identified as ''corner rivulet flow,'' ''falling film flow with dry patches,'' and ''complete falling film flow'' when liquid flow rate increased gradually. Besides liquid film flow in microchannels, a flooding presented as the flow of liquid along the side wall of gas chamber in FFMR was found at high liquid flow rate. Moreover, the flooding could be initiated at lower flow rate with the reduction of the depth of the gas chamber. CO 2 absorption was then investigated under the complete falling flow regime in FFMR, where the effects of liquid viscosity and surface tension on mass transfer were demonstrated. The experimental results indicate that k L is in the range of 5.83 to 13.4 Â 10 À5 m s À1 and an empirical correlation was proposed to predict k L in FFMR.

Numerical investigation is performed of the problem on stratified flow of two viscous incompressible fluids in a horizontal (and slightly inclined to the horizontal) plane-parallel channel. An algorithm is developed for the determination of the interface between fluids. The control volume approach and the SIMPLER algorithm are used to obtain the results. The following characteristic quantities are determined and analyzed in all versions of calculations for the water-oil system: flow field, pressure, fluid interface, friction on the channel walls, velocity profiles in the channel cross sections.
