TLDR
In this article, an analytical model for the rate of gas absorption into laminar non-wavy film flow on a horizontal rotating disk is obtained assuming short contact times, and it is established that the absorption process in the film on the disk as compared to that in a gravitational wavy flow can be intensified up to 14 times by means of a moderate rotation speed.Abstract:
An analytical model for the rate of gas absorption into laminar non-wavy film flow on a horizontal rotating disk is obtained assuming short contact times. Literature data for the oxygen mass transfer coefficient in a wavy film is correlated by means of the dimensionless numbers deriving from the model. The rate enhancement due to waves is found to vary from 6 to 13 times. It is established that the absorption process in the film on the disk as compared to that in a gravitational wavy film flow can be intensified up to 14 times by means of a moderate rotation speed.read more

Process intensification : heat and mass transfer characteristics of liquid films on rotating discs
A. Aoune,Colin Ramshaw +1 more
TL;DR: In this article, the theoretical and experimental performance of these thin films when performing heat and mass transfer to the disc and the surrounding gas, respectively, was examined and it was found that very high transfer coefficients can be achieved at modest disc speeds with water-like liquids.
