TLDR
In this article, two distinct mass-transfer regimes, associated with energy-containing and energy-dissipating turbulent motions, are identified, and a criterion, based on the turbulence Reynolds number, is determined for the applicability of each regime.About:

Theoretical prediction of volumetric mass transfer coefficients in bubble columns for Newtonian and non-Newtonian fluids
TL;DR: A theoretical model for volumetric mass transfer coefficients in bubble columns has been developed in this paper, based on Higbie's penetration theory and Kolmogoroff's theory of isotropic turbulence.

Turbulence in two-phase dispersed flows
T. G. Theofanous,J. Sullivan +1 more
TL;DR: In this article, a theoretical basis for the prediction of turbulence levels in two-phase flows is proposed, applied to dispersed-gas/liquid (bubbly) and solid/gas (particulate) two phase flows, for which experimental data are available.

Advances in understanding and modeling the gas–liquid mass transfer in shake flasks
TL;DR: In this paper, the authors present advances in understanding and modelling the gas-liquid mass transfer in shake flasks at water-like liquid viscosity in flask sizes between 50 and 1000 ml.
Journal ArticleDOI
Liquid-phase mass transfer coefficients in bioreactors.
TL;DR: A reasonable agreement between the model and the experimental data is found and the volumetric mass transfer coefficient obtained experimentally by the specific surface area estimated using the available correlations is found.

The theory of homogeneous turbulence
TL;DR: In this article, the kinematics of the field of homogeneous turbulence and the universal equilibrium theory of decay of the energy-containing eddies are discussed. But the authors focus on the dynamics of decay and not on the probability distribution of u(x).

An eddy cell model of mass transfer into the surface of a turbulent liquid
John C. Lamont,Donald S. Scott +1 more
TL;DR: In this paper, a model of the hydrodynamic behavior near the surface of a turbulent pipe flow of water is proposed to provide a link between the observed mass transfer behavior and the state of the turbulent field.

Decay of isotropic turbulence in the initial period
TL;DR: In this paper, the authors described direct measurements of all the terms in the equation for the rate of change of mean square vorticity in isotropic turbulence and with the experimental verification of some recent theoretical investigations.

On gas absorption into a turbulent liquid
G.E. Fortescue,J. R. A. Pearson +1 more
TL;DR: In this article, the authors provided a model for the process of re-aeration of polluted rivers and streams using a simple cellular model and compared with experimental results for absorption of CO2 into water in the flow behind a grip placed across the entrance to an open channel.
Journal ArticleDOI
Turbulence phenomena at free surfaces
TL;DR: In this paper, gas absorption by eddies at the free surface of a strongly turbulent liquid is interpreted quantitatively in terms of the Levich approach and the mass transfer coefficient is calculated to vary as Re to a relatively high power (1.3 to 1.5).
