Surface motion and gas absorption

Abstract

Abstract The influence of small surface waves on mass transfer from pure gases into water has been investigated. Small amplitude progressive two‐dimensional waves were mechanically generated at the liquid surface for the wave studies. Control experiments with nonwaved surfaces were also conducted. An effective diffusivity was used to correlate the data. Marked increases in mass transfer over that predicted by molecular diffusion for the no‐wave control runs are attributed to natural convection motions, and are probably caused by density and surface tension variations.
