The liquid phase rate-controlled transport of C02 across a gas/liquid interface into water was studied using a non-invasive laser-induced fluorescence (LIF) technique. Turbulence in the liquid layer was generated by a vertically-oscillating grid. The CO2/water interface was cleaned by removal of surface water with additive-free lens paper, or 100% rayon cloth followed by surface vacuuming with a glass Pasteur pipette. The liquid phase mass transfer coefficient kL was measured under conditions of varying turbulence intensity and scale for each surface cleaning procedure. Transport rates were also measured for an uncleaned surface and in the presence of a deliberately created organic monolayer. All of the results were used to test the surface renewal models of Fortescue and Pearson and Lamont and Scott. A model for wind-dominated gasiliquid transfer developed by Cohen was used to relate the present data to kL measurements for gas exchange in wind tunnels. This comparison indicates that wind tunnel results may be related to stirred-tank experiments using the turbulent dissipation rate Ԑ and a surface renewal model.DOI: 10.1111/j.1600-0889.1986.tb00256.x
