Rainwater runoff from building facades is a complex process governed by a wide range of
urban, building, material and meteorological parameters. Given this complexity and the wide …

Two-phase annular flow in vertical pipes is one of the most common and important flow
regimes in fluid mechanics, particularly in the field of building drainage systems where …

A variety of gas− liquid microchannel reactors have been developed so far, using different
contacting principles. Some devices utilize continuous-phase contacting (ie, nondispersed …

A simultaneous measurement technique based on planar laser-induced fluorescence
imaging (PLIF) and particle image/tracking velocimetry (PIV/PTV) is described for the …

The evolution of solitary waves into three‐dimensional (3‐D) waves was experimentally
observed on a vertically falling water film at mainly Re= 10–100. At Re greater than 40, 2‐D …

The hydrodynamics of downwards gas–liquid annular flows and falling films in a pipe were
studied experimentally using simultaneous planar laser-induced fluorescence and a …

Hydrogenation of nitrobenzene to aniline in ethanol was performed continuously in a
microstructured falling film reactor at 60° C, 1–4bar hydrogen pressure and residence time 9 …

The Editor-in-Chief has retracted this article. The article was submitted to be part of a guest-
edited issue. An investigation by the publisher has found that the editorial handling and peer …

In response to the worldwide need for more sustainable chemical processes, distillation
became target of major efforts for efficiency improvement. Leveraged by process …

Falling liquid films and downward cocurrent flows in rounded shape pipes have been
experimentally studied during the last decades, estimating the evolution of its major …
