Models for air-water gas transfer: an experimental investigation.

Abstract

The air-water transfer velocities for H2, He and Xe have been measured simultaneously in laboratory-tank experiments. Using average values from the existing literature data for the molecular diffusivities of the gases, the transfer velocities are found to vary with the diffusivity raised to the power 0.57. This exponent is in reasonable agreement with the findings from other laboratories, as well as field studies, provided average diffusivities are used consistently. -from Authors
