TLDR
In this article, the effects of liquid viscosity and interfacial shear on the liquid side mass-transfer coefficient for turbulent falling films were investigated and the transition from wavy laminar to turbulent flow occurred at Reynolds numbers from 1000 to 1200.About:

Direct contact condensation and momentum transfer in turbulent separated flows
E.D. Hughes,Romney B. Duffey +1 more
TL;DR: In this article, a turbulent eddy-based surface renewal theory for condensation and evaporation of saturated vapor onto or from its liquid is proposed, which accurately predicts experimental data for horizontal, concurrent condensation of steam on water.

Flow characteristics and circulatory motion in wavy falling films with and without counter-current gas flow
TL;DR: In this paper, a laser-induced photochromic tracer technique was used to investigate the flow structure in a thin, wavy falling liquid film in a vertical tube both with and without interfacial shear induced by a counter-current flow of gas.

Siu-Ming Yih,Kai-Yune Chen +1 more
TL;DR: In this article, the authors measured liquid-side mass transfer coefficients for absorption of CO2 and O2 into falling water films on the outside of a stainless steel pipe 2.72 cm OD and 183 cm absorption length.

Simultaneous heat and mass transfer in absorption of gases in turbulent liquid films
TL;DR: In this paper, a theoretical analysis of the combined heat and mass transfer process taking place in the absorption of a gas or vapor in a turbulent liquid film is presented, where Eddy diffusivity correlations have been used to describe the transport near the wall and the interface and in the bulk of the film.

Correlation of the effects of viscosity and surface tension on gas absorption rates into freely falling turbulent liquid films
Y.S. Won,A.F. Mills +1 more
TL;DR: In this paper, experimental data for gas absorption into freely falling turbulent liquid films are presented, where carbon dioxide was absorbed into methanoi and aqueous propanol solutions at 25°C to obtain a surface tension range of 22.2 − 72 × 10− 3N/m.

Gas absorption into a turbulent liquid
TL;DR: In this paper, mass transfer coefficients were measured for the liquid phase for gas absorption into a turbulent liquid flowing down a long wetted-wall column, and the results were interpreted in terms of an eddy diffusivity model and indicate that the eddy diffusion increases as the square of the distance from the interface.
