Marangoni instability in binary liquid–liquid systems

Marangoni instability of immiscible liquid–liquid stratified flow with a planar interface in the presence of interfacial mass transfer

“…It was shown that Marangoni instability also happens in the region of small Reynolds number (less than 1). This is in accordance with the result of Slavtchev and Mendes, where mass transfer from water into ethylacetate (m = 2.174) [21] and that of Perez de Ortiz and Sawistowski, where mass transfer from isobutanol into water (m = 3.46) [22]. The unstable region is complex for l = 4.…”

Transient rise velocity and mass transfer of a single drop with interfacial instabilities – experimental investigations

“…The first efforts to predict theoretically interfacial instability in a liquid/liquid system with a plane interface were made by Sternling and Scriven (1959). More general approaches were developed by Hennenberg et al (1979Hennenberg et al ( , 1980, Nakache et al (1983), Slavtchev et al (1998) and Slavtchev and Mendes (2004) and Slavtchev et al (2006) show in a linear stability analysis for a system with a planar interface that the onset for temperature driven Marangoni instabilities depends on the three parameters diffusivity ratio, kinematic viscosity ratio and the product of the heat of solution and the thermal interfacial tension coefficient. The predictions are compared with experiments showing both success and failures.…”

Interfacial Convection in Multilayer Systems

“…The stability criteria in this case have been obtained theoretically (Perez de Ortiz and Sawistowski, 1973a) and compared with the experimental observation (Perez de Ortiz and Sawistowski, 1973b). The problem has been recently revisited by Slavtchev and Mendes (2004). Let us discuss now the spontaneous motion of a droplet located at the interface of a liquid solution.…”
