In a nonequilibrium multiphase system, the Marangoni effect has important influence on interphase heat and mass transfer induced by interfacial tension gradient associated with either solutal or thermal gradients in numerous applications. Although the basic knowledge of the Marangoni effect has made great progress, its mechanism is not yet fully recognized. An in-depth understanding of the basic principles of heat and mass transport induced by the Marangoni effect is important for better operation of interphase transfer units. This report aims to provide a systematic study of the mechanisms of the Marangoni effect. Special foci are concentrated on the field of material processing, which encompasses the process wherein the raw materials are transformed into useful engineering products. A series of experimental, theoretical, or simulated results are extracted from the literature to elucidate the mechanism of the Marangoni effect and to rationalize the interphase transport phenomena. We examine the major physical explanations and attempt to distinguish the working principle behind the process. Perspectives are also proposed to trigger further innovative thinking about the topics. This work provides new insight into material processing by taking advantage of the Marangoni effect and has far-reaching implications in the design of future nonequilibrium multiphase system.
