“…Generally three different flow patterns have been recognized which is in compliance with the findings of Zhang et al (2010). Specifically for low flow rates it can be observed that the liquid is concentrated at the corners of the microchannel forming two rivulets (due to the hydrophilic nature of the PMMA) while there is a dry stripe at the middle of the microchannel (corner rivulet flow, Figure 4.3a).…”

“…4.5 and eq. 4.6 to predict MWF in microchannels is also reported by (Zhang et al, 2010). In this work MWFdcr is investigated for microchannels with different geometrical characteristics but only for vertical orientation.…”

“…The principle of falling film microreactors have been adapted and utilized by several flow chemistry research groups over the past few years. Recently Chen and coworkers 133 designed a novel double-side falling film microchannel contactor, and investigated the absorption coefficient of carbon dioxide in water. A similar design was shown by Steinfeldt and co-workers 134 investigating the cyanide degradation via ozone absorption as well carbon dioxide absorption.…”

“…It is noted that the existing studies on Marangoni effect mainly focused on the falling film flow over an infinite plate (open plate). However, the falling film flow usually happens on a confined space with restricted sidewalls [20,21] in the practical applications. The falling film flowing over a vertical plate with sidewalls will present quite different flow characteristics from the flow without sidewalls due to the corner effect.…”
