摘要：

The paper investigates mass transfer with a chemical reaction in conditions of spontaneous interfacial convection (Marangoni effect). It is shown that a chemical reaction changes the ratio of phase resistance, with the result that the balance of forces at the surface is disturbed and interfacial instability is initiated. The effect of the concentration and the surface activity of a transferred reagent on the conditions of initiation of interfacial instability and the intensity of interfacial convection has been investigated. The determining parameters are the ratio of phase resistances, the surface activity and the concentration of a transferred reagent. (C) 2001 Elsevier Science B.V. All rights reserved.
