Notes:
Concentration profiles for carbon dioxide diffusion into thin water films with waves flowing down an inclined plate have been determined. Film Reynolds numbers were varied from 732 to 1,834 at a cell angle of inclination of 9 deg. 44 min. Total diffusivities measured from the concentration profiles showed a marked increase in the central region of the film, with the diffusivity tending toward the molecular diffusivity at the boundaries of the film. Interferometer pictures of the concentration profile showed that the effect of the waves was to compress and expand the profile as the surface of the film changed, but indicated no direct effect on the variation of eddy diffusivity normal to the liquid surface.
