Abstract

Results generated by solving the one-dimensional mass transfer equation for gas transfer in the near-surface region of water bodies are compared with experimental data The data were obtained in temperature controlled cylindrical water tanks in which agitation was induced by propellers. Mass transfer was studied for methane, eurylene, and acetylene The results show good agreement between theory and data for a broad range of agitation conditions A theoretical power law approach between two relevant nondimensional groups is observed in this range, but deviations from this trend may be observed for both very low and very high agitations. The fact that t
