Turbulent surface film thickness for oxygen absorption in open channel flows / Y.L. Lau.: En36-522/103-1975E-PDF

"The absorption of atmospheric oxygen into an open-channel flow is controlled by a small region near the free surface where the concentration gradient is large and the diffusivity is small. Data from reaeration experiments in an open-channel is used to calculate the thickness of the turbulent film, using some assumed values of diffusivity. It is shown that the dimensionless film thickness varied inversely as the shear Reynolds number and was also dependent on the channel roughness"--Abstract.
