TLDR
In this paper, mass transfer rates between solid nickel surfaces and the ferro-ferri-cyanide electrolyte flowing in a 1 in.square duct have been measured for smooth and six similar rough surfaces, the latter having V-shaped grooves of 2-14 mil depth normal to the flow direction.About:

On the parameters influencing air-water gas exchange
TL;DR: In this article, the Schmidt number dependence of the transfer velocity k changes from k ∝ Sc−⅔ to k √ Sc−½, indicating a change in the boundary conditions at the surface.

Hydrodynamics of Coral Reefs
TL;DR: The geometric complexity of coral reefs leads to interesting fluid mechanics problems at scales ranging from those of coral colonies or even branches a few millimeters in diameter up to whole reefs that can be kilometers in horizontal extent.

Mass-Transfer Measurements by the Limiting-Current Technique
TL;DR: Limiting current density refers to the maximum rate at 100% current efficiency at which a particular electrode reaction can proceed in the steady state as discussed by the authors, determined by the composition and transport properties of the electrolytic solution and by the hydrodynamic condition at the electrode surface.

TL;DR: In this article, a review of known and unknown aspects of wet and dry fluxes of atmospheric trace constituents past the air-sea interface is presented, and a resistance model for dry deposition illustrates that the rate-limiting stage of dry removal can occur in different layers depending on atmospheric and oceanic conditions and on properties of the pollutants.

TL;DR: In this article, mass transfer rates were measured for smooth pipe sections of benzoic acid dissolving in glycerine-water solutions and the data were correlated with an average deviation of 5·4 per cent by the equation NSh = 0·0096 NRe0.913NSc0·346 The data fall 5 to 10 per cent below the correlation of Friend and Metzner [2] and 20 to 100 per cent above other published correlations.

Measurement of instantaneous rates of mass transfer to a small sink on a wall
TL;DR: In this article, a technique for measuring the average rate of transfer and the fluctuations in the transfer rate at a small source or sink on a wall was developed for measuring flow pattern in the vicinity of the wall.
