Intensification of mass transfer and reaction in electrically disturbed liquid-liquid systems
2017, Chemical Engineering JournalCitation Excerpt :Several techniques are presented in the literature for overcoming this problem. Berg and Morig [4], Orell and Westwater [24], and Bakker et al. [2], In the current work the cell design of Bakker et al. was adapted for the experiments as shown in Fig. 4.
Relaxation oscillations of solutal Marangoni convection at curved interfaces
2015, Colloids and Surfaces A: Physicochemical and Engineering AspectsCitation Excerpt :These regions of mixed fluid are separated from the organic bulk phase by a high-contrast concentration front arching over the center of the interface in Fig. 4(a) and the lateral sides in (b), respectively. In [17,48], the influence of small deformations of an ideally planar interface was already briefly discussed. However this effect becomes particularly clear in Fig. 4((a) and (b)) by deliberately imposing a strong variation of curvature.

2014, Journal of Membrane ScienceDirect microscopic observation of membrane formation by nonsolvent induced phase separation
2013, Journal of Membrane ScienceCitation Excerpt :We further hypothesize that finger-like macrovoids can be formed in other PSf-DMF polymer solutions provided that these films are cast in a dry environment prior to immersion in a nonsolvent bath. Mass transfer through liquid interfaces is often associated with large convective flows near the interface [7,41–46]. Frommer and Messalem suggested that the formation of large finger-like macrovoids in polymer solutions are caused by convective flows [7].
Relaxation oscillations between Marangoni cells and double diffusive fingers in a reactive liquid-liquid system
2012, Chemical Engineering ScienceCitation Excerpt :Indeed, the impact of Rayleigh–Taylor or double diffusive convection on the critical conditions of the interacting instabilities has been investigated both experimentally and by linear stability analysis (Berg and Morig, 1969; Gumerman and Homsy, 1974; Tanny et al., 1995; Bratsun et al., 2005; Grahn, 2006). However, a detailed study of the influence on the characteristic features of Marangoni flow patterns is lacking despite certain hints in the work of Berg and Morig (1969) where the convection patterns were examined for the case of pure mass transfer. By varying the composition of the organic phase, they modified the resulting density profiles for the mass transfer of the solute.
