Abstract

A theory of evaporation from a plane, free-liquid surface was first introduced by O. G. Sutton. However, in recognizing the shortcomings of Sutton’s theory, F. Pasquill proposed a generalized theory—that is, to modify Sutton’s theory by replacing the air viscosity in the Sutton model with the molecular diffusivity. To verify his theory, Pasquill also carried out a series of experiments. In this study, the author further considers the modification of the Sutton–Pasquill theory by introducing a Schmidt number of −2/3 and provides some theoretical justifications. The results are in very good agreement with the experimental data. In addition, a two-layer evaporation theory that includes an interfacial sublayer is developed.
